This is a follow up to [38065] to ensure that `wp.html.string()` always
converts empty `alt` attributes to `alt=""` rather than returning HTML using
empty attribute notation, like `alt`. This allows screen readers to ignore
images with empty `alt` attributes, rather than reading out the URL string.
Additionally this completely removes the logic in `wp.html.string()` for
converting blank attributes to empty attribute notation since empty attribute
notation is generally meant to denote a boolean value, e.g.,
`checked` == `checked="checked"`, which doesn't apply in this context because
boolean attributes must be omitted in order to represent a `false` value.

* Reactivates the `wpgallery` and `wpeditimage` TinyMCE plugins. Deactivates the `wpviews` TinyMCE plugin.
* Moves still-relevant logic from `mce-views.js` to `media-upload.js` and `shortcode.js`.
* No longer include `wp-includes/js/mce-views.js`. This code will not be used in 3.5, and should be considered unstable.
* Currently, this is the real 3.4 experience; as such, editing triggers the old modals. Changing this is the next major step.
When reassessing views, we should look over all of these tickets and anticipate these bugs accordingly.

'''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.

Adds `wp.shortcode`, a set of methods used for parsing shortcodes out of content. Also adds a default set of shortcode properties to `wp.mce.view`.
