Comment:

 Updated the patch with latest progress:

 * Abstracts `wp.media.gallery` code in `wp.media.collection` which
 `wp.media.gallery`, `wp.media.playlist`, and `wp.media['video-playlist']`
 use.
 * Abstracts `wp.media.controller.GalleryAdd` and
 `wp.media.controller.GalleryEdit` into `wp.media.controller.CollectionAdd`
 and `wp.media.controller.CollectionEdit` which all 3 use with minimal
 registration code
 * Allows any new types/shortcodes to be simply added by convention with a
 few lines of code, the only excessive code is registering new Toolbars and
 Menus when you add a new type, there really isn't any way around it
 * Adds TinyMCE view switch for `[playlist]` and `[video-playlist]` using
 the `wpplaylist` plugin, which I added. Theoretically, all media
 shortcodes could use the same TinyMCE plugin - all it does it turn a
 shortcode into HTML and the reverse. Adding another plugin each time seems
 excessive.
 * Abstracts the shortcode handlers for `[playlist]` and `[video-playlist]`
 into one helper function:
 {{{
 function wp_playlist_shortcode( $attr ) {
         return wp_get_playlist( $attr, 'audio' );
 }
 add_shortcode( 'playlist', 'wp_playlist_shortcode' );

 function wp_video_playlist_shortcode( $attr ) {
         return wp_get_playlist( $attr, 'video' );
 }
 add_shortcode( 'video-playlist', 'wp_video_playlist_shortcode' );
 }}}

 The player on the front end will use a `MediaElementPlayer` object and
 some custom Backbone Views. The ME class is necessary to control the
 player from code and sequence tracks / support next-prev, etc. Next steps
 will be skinning the audio player to show metadata and images.

 This code actually works now - audio and video, all clips will play one
 after the other.

 Gonna shoot for this or something like it in 3.9.
