- Add wp.media.events which is intended to be a global media event bus.
- Add a post-render event to the ImageDetails view that third-party code can leverage to add subviews.
- Performance improvement for the initialization of the PostImage model.
- A bit more markup to the image details template to make it easier to add a view to the advanced options.

- Switch to using <select> for the Size and Link To.
- Bring back the field for CSS Class for the image, but don’t incorporate the internally managed WordPress classes (size-, wp-image-, etc…).
- On larger screen sizes, float labels to the left. When the width drops below 900px, stack the label above the fields.
- Keep image at top on screen sizes where the two columns are stacked into a single column.
- Don't replace the nodes in the editor DOM so we don't stomp on any custom attributes that the user may have added via the Text editor or some other mechanism.

- Make the layout two-column for wider screens, remove the sidebar, and shrink the modal a bit.
- The image reflects the size as inserted in the post as long as it doesn't overflow the column and is not too tall. Changing the size to another intermediate will also update the image "preview."
- Rename "Edit Image" to "Edit Original" to try and better communicate that editing the image will modify the media library item not just the image inserted into the post that is being edited.

* Move audio and video tag builder logic in `media-template.php` into PHP funcs that can be reused by any code passing `data.model` to an Underscore template
* Pause all players when moving between editor tabs and when moving from the editor to editing in the media modal.
* Rename `wp.media.audio|video.shortcode()` to the more appropriate `wp.media.audio|video.update()` that now returns a `wp.shortcode` object instead of a string.
* Add necessary MediaElement css files to `$mce_css`

* `Collection#get()` now accepts `cid`s. `Collection#getByCid()` has been removed.
* When overriding the `State` constructor, bind `change` callbacks after the default `Model` constructor is called, because the `Model` constructor no longer passes the `silent` flag when calling `set()` for the default attributes.
* In 'change' events, `options.changes` was removed. It can now be accessed through `model.changed`. Check if any attributes have changed by calling `model.hasChanged()`. Also, don't mess with `model.changed`; it persists beyond the scope of a single event.
* `options.index` is no longer be set in the `add` event callback. Use `collection.indexOf(model)` can be used to retrieve the index of a model instead.

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.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 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`.
