This restores linking to media files as the default, over attachment pages. This 'default' cannot currently be changed by a user setting (per 3.4 behavior), due to the default database schema.

The attitude of a neditor is best described as cranky optimism. Younger organisms are more eager, but quickly tire after working on little sleep. They eventually evolve into the cranky optimism stage in a process that generally takes three to five months.

We tried in vain -- a noble but ultimately failed effort -- to reduce the number of fields for attachments from four (title, caption, alt, description) to one (caption for images, title otherwise). Alternative text needed to stay for accessibility reasons, of course.
Eventually title returned due to heavy plugin reliance. Description is too used by too many plugins (often times incorrectly -- the caption is more likely the proper field), hence its less-than-triumphant return today.
Version 3.5 has tried to streamline media in a number of ways. Removing fields may have been too much at once, as it forced not only a user interface change, but a paradigm change as well.
Finally, on upload we populate the description field with IPTC/EXIF captions, rather than the caption field. See #22768, this should be fixed. For now, Description stays.
This commit also restores 'Title' attribute editing to the main tab of the Edit Image dialog. The "Title" field no longer populates title attributes for <img> tags by design (for accessibility and other purposes, see #18984). So, here is a more obvious 'workaround' for the tooltip community.
Finally, this:
* Cleans up the post.php attachment editor, including by showing a prettier form of the mime type.
* Enables plugins to specifically hide attachment_fields_to_edit from either post.php (where you can create meta boxes) or the modal (which you may not want to clutter), for compatibility reasons.
* Hides the 'Describe this file...' placeholder when a field is read-only in the modal.

Most users don't realize that the Featured Image meta box exists; if they do, few use it.
Restores the old meta box UI, including the admin_post_thumbnail_html filter. If a plugin is using _wp_post_thumbnail_html() in conjunction with Thickbox elsewhere, it will also magically still work.
Specific underlying changes:
* Converts the modal view to use the view manager, which means that a call to open() will automatically call render and attach if necessary.
* Doesn't automatically set a state in wp.media, to allow code to customize the states to be added before activation.

`wp.mce.media`
* Watch all workflows for the `insert` event and attempt to insert the current state's `selection` if it exists.
* Fetch and pass attachment display properties through to `wp.media.string.image()`.
`wp.media.controller.Region`
* Separate the concept of events and modes.
* All events triggered on a `Region` trigger both `event` and `event:mode` callbacks.
* When a mode is deactivated, `deactivate` and `deactivate:mode` events are fired.
* When a mode is activated, `activate` and `activate:mode` events are fired.
`wp.media.controller.Library`
* Remove the `details()`, `buildDetails()`, and `clearDetails()` methods that juggled sidebar views. Instead, handle the sidebar views using modes.
`wp.media.controller.Gallery`
* Shift the overloaded `sidebar()` method to use modes.
`wp.media.view.MediaFrame.Post`
* Declare `activate:mode` event bindings using an nested object to reduce repetition.
* Update sidebar activation callbacks.
`wp.media.view.Settings`
* Refactor to leverage HTML data attributes and implicit values (instead of setting the fallback whenever an object was created). This has the additional benefit that gallery shortcode parameters are not output when the user has left them set to the default.

* If a request has already been sent out for more attachments, return that request object instead of creating another.
`wp.media.controller.Region`
* A region allows views to be swapped in and out of a section of the page without either view having to know about the other.
* Application components can use the same callbacks and resources by leveraging `Region.mode()`, which triggers a set of callbacks to create or transform the current view, but only if necessary.
`wp.media.view.Frame`
* Leverage `Region` controllers instead of forcing states to swap view objects, which causes states to fit more comfortably in the controller-camp.
* Add `previous()`, a method to fetch the previous state `id`.
* Separate out the default settings over several objects (so blank frames can be instantiated).
`wp.media.view.MediaFrame`
* The base `Frame` used for media management: handles integration with the `Modal` and `UploaderWindow` views.
`wp.media.view.MediaFrame.Post`

`{{ a }}` - escaping

The main goal here is to rearrange the media components in a modularized structure to support more linear workflows. This is that structure using the pre-existing workflows, which will be improved over the course of the next few commits.
This leaves a few pieces a bit rough around the edges: namely gallery editing and selecting a featured image.
The fine print follows.
----
'''Styles'''
* Tightened padding around the modal to optimize for a smaller default screen size.
* Added a light dashed line surrounding the modal to provide a subtle cue for the persistent dropzone (which is evolving into a power user feature since we now have a dedicated `upload` state).
* Add a size for `hero` buttons.
* Remove transitions from frame subviews (e.g. menu, content, sidebar, toolbar).
----
'''Code'''
`wp.media.controller.StateManager`
* Don't fire `activate` and `deactivate` if attempting to switch to the current state.
`wp.media.controller.State`
* Add a base state class to bind default methods (as not all states will inherit from the `Library` state).
* On `activate`, fire `activate()`, `menu()`, `content()`, `sidebar()`, and `toolbar()`.
* The menu view is often a shared object (as its most common use case is switching between states). Assign the view to the state's `menu` attribute.
* `menu()` automatically fetches the state's `menu` attribute, attaches the menu view to the frame, and attempts to select a menu item that matches the state's `id`.
`wp.media.controller.Library`
* Now inherits from `wp.media.controller.State`.
`wp.media.controller.Upload`
* A new state to improve the upload experience.
* Displays a large dropzone when empty (a `UploaderInline` view).
* When attachments are uploaded, displays management interface (a `library` state restricted to attachments uploaded during the current session).
`wp.media.view.Frame`
* In `menu()`, `content()`, `sidebar()`, and `toolbar()`, only change the view if it differs from the current view. Also, ensure `hide-*` classes are properly removed.
*
`wp.media.view.PriorityList`
* A new container view used to sort and render child views by the `priority` property.
* Used by `wp.media.view.Sidebar` and `wp.media.view.Menu`.
* Next step: Use two instances to power `wp.media.view.Toolbar`.
`wp.media.view.Menu` and `wp.media.view.MenuItem`
* A new `PriorityList` view that renders a list of views used to switch between states.
* `MenuItem` instances have `id` attributes that are tied directly to states.
* Separators can be added as plain `Backbone.View` instances with the `separator` class.
* Supports any type of `Backbone.View`.
`media.view.Menu.Landing`
* The landing menu for the 'insert media' workflow.
* Includes an inactive link to an "Embed from URL" state.
* Next steps: only use in select cases to allot for other workflows (such as featured images).
`wp.media.view.AttachmentsBrowser`
* A container to render an `Attachments` view with accompanying UI controls (similar to what the `Attachments` view was when it contained the `$list` property).
* Currently only renders a `Search` view as a control.
* Next steps: Add optional view counts (e.g. "21 images"), upload buttons, and collection filter UI.
`wp.media.view.Attachments`
* If the `Attachments` scroll buffer is not filled with `Attachment` views, continue loading more attachments.
* Use `this.model` instead of `this.controller.state()` to allow `Attachments` views to have differing `edge` and `gutter` properties.
* Add `edge()`, a method used to calculate the optimal dimensions for an attachment based on the current width of the `Attachments` container element.
* `edge()` is currently only enabled on resize, as the relative positioning and CSS transforms used to center thumbnails are suboptimal when coupled with frequent resizing.
* Next steps: For infinite scroll performance improvements, look into absolutely positioning attachment views and paging groups of attachment views.
`wp.media.view.UploaderWindow`
* Now generates a `$browser` element as the browse button (instead of a full `UploaderInline` view). Using a portable browse button prevents us from having to create a new `wp.Uploader` instance every time we want access to a browse button.
`wp.media.view.UploaderInline`
* No longer directly linked to the `UploaderWindow` view or its `wp.Uploader` instance.
* Used as the default `upload` state view.
`wp.media.view.Selection`
* An interactive representation of the selected `Attachments`.
* Based on the improved workflows, this is likely overkill. For simplicity's sake, will probably remove this in favor of `SelectionPreview`.

* Also moves most of the `Frame` view's `createSelection` method to a real `Selection` model (which inherits from the `Attachments` model).
* Properly assigns the library within the `Gallery` state, allowing for the `Gallery` state to inherit from the `Library` state.

* Adds `wp.media.view.Sidebar`, to aid in rendering the sidebar.
* Removes the `directions` from the `Attachments` view and shifts search into a separate view (`wp.mce.view.Search`) that can be relocated at will. This also serves to simplify the `Attachments` view by removing the nested `list` and `$list` parameters.
* Show the toolbar on the featured image workflow, effectively requiring confirmation before closing the dialog.

Revises the concept of the media controller and workspace views (i.e. two central points of control) to be more granular. The main media object is now the `Frame`, which is a hybrid view and state machine.
The state machine is a collection of states, which are just generic instances of `Backbone.Model`. This circumvents the problem of juggling global parameters when changing states. Each state contains its own event loop. All events are also forwarded to the frame itself (as is the case in all model/collection relationships).
The frame view contains several regions, each of which can be overridden without harming or re-rendering the other regions. These work well when used in conjunction with the state machine events.
This removes the upload sidebar (don't worry, visible upload UI will return). Drag and drop uploading still works. The ability to upload has been abstracted into its own view (instead of being attached to the central workspace view).
Editing galleries is temporarily broken — the gallery creation and editing experiences will be unified in a future patch.
Adds events to detect dragging changes in `wp.Uploader` and adds methods to detect and leverage browser support for CSS3 transitions.

* Adds a `describe` option to the workflow controller to support inline caption editing.
* For images, descriptions are mapped to the `caption` attribute.
* For other media items, descriptions are mapped to the `title` attribute.
* Descriptions are saved when the textarea's `change` event fires (i.e. when the textarea is blurred).

'''Galleries'''
* Gallery insertion from the new media modal (into TinyMCE, the text editor, etc).
* Gallery previews in TinyMCE now use the `wp.mce.views` API.
* Disables the TinyMCE `wpgallery` plugin.
* Gallery previews consist of the first image of the gallery and the appearance of a stack. This will later be fleshed out to include more images/functionality (including editing the gallery, gallery properties, and showing the number of images in the gallery).
* Multiple galleries can be added to a single post.
* The gallery MCE view provides a bridge between the `wp.shortcode` and `Attachments` representation of a gallery, which allows the existing collection to persist when a gallery is initially created (preventing a request to the server for the query).
'''Shortcodes'''
* Renames `wp.shortcode.Match` to `wp.shortcode` to better expose the shortcode constructor.
* The `wp.shortcode` constructor now accepts an object of options instead of a `wp.shortcode.regexp()` match.
* A `wp.shortcode` instance can be created from a `wp.shortcode.regexp()` match by calling `wp.shortcode.fromMatch( match )`.
* Adds `wp.shortcode.string()`, which takes a set of shortcode parameters and converts them into a string.* Renames `wp.shortcode.prototype.text()` to `wp.shortcode.prototype.string()`.
* Adds an additional capture group to `wp.shortcode.regexp()` that records whether or not the shortcode has a closing tag. This allows us to improve the accuracy of the syntax used when transforming a shortcode object back into a string.
'''Media Models'''
* Prevents media `Query` models from observing the central `Attachments.all` object when query args without corresponding filters are set (otherwise, queries quickly amass false positives).
* Adds `post__in`, `post__not_in`, and `post_parent` as acceptable JS attachment `Query` args.
* `Attachments.more()` always returns a `$.promise` object.

* Removes the wpeditimage TinyMCE plugin from the default plugins array.
* Add `wp.media.fit`, a helper method to constrain dimensions based upon a maximum width and/or height.
* Add html attribute parsing and string generation utilities (currently stored in mce-views).
* Calling `remove` on a TinyMCE views now ensures that the the parent and references are removed as well.
* Fixes a bug where we weren't sending the full array of results to matches in wp.mce.view.

Remove the UI for setting the default width and height for embeds. Width was confusing as it
was blank by default (inheriting the content width from the theme, or 500px). The height is
now calculated as 1.5x the content width, or 1000px, whichever is smaller.
The [embed] shortcode can still receive manual height and width attributes. This just removes
the global settings.

* Taxonomies attached to the media library now appear in the admin menu (if show_ui).
* Editing, cropping, uploading, etc. is still very rough, but mostly functional.
API-wise:
* New function: get_taxonomies_for_attachments(). Like get_taxonomies(), for taxonomies specifically registered against attachments.
* Brings taxonomy support from the posts list table to the media list table. Expect them to converge soon.
* wp_insert_attachment() now handles taxonomies like wp_insert_post(). Also expect them to converge soon.
* New edit_form_after_title hook.

Please note that this commit does not integrate media into the existing UI. If you would like to see the new UI, navigate to the post editor and run the following in your browser's Javascript console:
new wp.media.controller.Workflow().render().modal.open();
The Javascript is broken up into two files, with the slugs media-models and media-views.
* media-models: The models are UI agnostic, and can be used independent of the views. If you'd like to create custom UIs, this is the script for you.
* media-views: This is the Media Experience. The views (and controllers) depend on the models (which are listed as a dependency and will automatically be included thanks to wp_enqueue_script). The views also require the media templates, media-view styles, and the plupload bridge settings. Perhaps we should create a function to include the whole shebang, but in the meantime...
To include media-views in the admin, run the following PHP in or after 'admin_enqueue_scripts':
wp_enqueue_script( 'media-views' );
wp_enqueue_style( 'media-views' );
wp_plupload_default_settings();
add_action( 'admin_footer', 'wp_print_media_templates' );

wp.Uploader is a wrapper that provides a simple way to upload an attachment (using the wp_ajax_upload_attachment handler). It is intentionally decoupled from the UI. When an upload succeeds, it will receive the attachment information (id, url, meta, etc) as a JSON response. If the upload fails, the wrapper handles both WordPress and plupload errors through a single handler.
As todos, we should add drag classes for the uploader dropzone and account for the rough 100mb filesize limit in most browsers. The UI for the customizer upload controls could be improved as well.
