* Playlists operate like galleries in the admin.
* Provide default UI and JS support in themes using MediaElement and Backbone.
* The shortcodes are clickable, editable, and configurable using the media modal.
* Playlists support images for each item, whether or not the current theme supports images for `attachment:audio` and `attachment:video`
* Playlists respond to `$content_width` and resize videos accordingly.
* All playlist data is included inline, using a script tag with `type="application/json"`, allowing anyone to unenqueue the WP playlist JS and roll their own.
* Playlist styles are minimal and work out of the box in the last 5 default themes. They inherit and adapt to the current theme's font styles, and their rules are easily overrideable.

While uploading, we know an attachment's filename but not its mime type. Check specifically for extensions. Check for type as a convenience when it is available.

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.

* 'Random' to 'Random Order', to be clear what it controls.
* 'Describe this image...' to 'Caption this image...', to be clear it links to the Caption field and not the revived Description field, see [23083].
