In PHP 5.3.0, `is_a()` is no longer deprecated, and will therefore no longer throw `E_STRICT` warnings.
To avoid warnings in PHP < 5.3.0, convert all `is_a()` calls to `$var instanceof WP_Class` calls.
`instanceof` does not throw any error if the variable being tested is not an object, it simply returns `false`.

Up to this point, various core elements' DocBlocks incorrectly included an `@internal` tag as a means for skipping the parsing process. When paired with a description (inline or otherwise), `@internal` is a valid tag meant to provide internal-only context, but not necessarily to skip parsing the entire element.

* Add a third argument to `WP_Scripts->print_extra_script()`, `$key`, which will be passed to `->get_data()` (no longer passes hardcoded `'data'`)
* When `$key` is set to `'data-after'`, the inline script will be printed after the `<script>` tag. If the scripts are being concatenated, all scripts' `'data-after'` data will be printed after the concatenated `<script>` has been rendered.
Props hakre, wonderboymusic.

* Bump MediaElement script loader versions to 2.16.2 - missed in [30634], oops!
* Add `Froogaloop` to `js/mediaelement` scripts for Vimeo
* Check for Vimeo in the same locations that YouTube is checked
* Dynamically load Froogaloop script in admin when editing a TinyMCE view
* Edit MediaElement to call `mejs.$.extend` instead of `$.extend` in `mejs.HtmlMediaElementShim.createPlugin()`, since `$` is not available via WP's jQuery (I will report this upstream):

* the "DFW" button is now an auto/off toggle
* defaulting to auto during beta, decide later for release
* "auto" means that DFW gets enabled as you start typing in editor
* tabbing and mousing out will bring the full interface back
* there is a slight grace period during which your mouse can quickly return

* Support a `caption` attribute for audio and video shortcodes
* In `wp.media.audio|video`, rename `update` to `shortcode` to allow these models to share the same mixins as `wp.media.collection` subclasses
* When sending an audio or video shortcode to the editor, create a default caption if the user hasn't entered one. This currently only displays in the editor, not on the front end. Captions aren't tied to a specific attachment here because external sources are supported.
* In the `wp.mce.media` mixin, in the `edit` method, read `attr` instead of `data` when attempting to parse the encoded shortcode. `data` does not automatically update when the attribute changes. This was a blessing to debug.
* Add `wp.mce.media.PlaylistView` to support playlist views in TinyMCE
* Expose `WPPlaylistView` to global scope and suppress auto-parsing of playlist nodes when in the admin. Allow `WPPlaylistView` to be passed `metadata` on creation instead of requiring a JSON blob to be parsed.
* Remove all of the playlist logic from the `wpgallery` TinyMCE plugin.
* In `wp_prepare_attachment_for_js()` return more data for audio/video so that playlists can have parity in the admin/front end.

* Remove the audio/video shortcode parsing from the `wpgallery` plugin.
* Make `mce-view` a dependency of `media-audiovideo`
* Introduce `wp.mce.video`, `wp.mce.audio`, `wp.mce.media`, and `wp.mce.media.View`
* Rename `wp.media.audio|video.shortcode()` to `wp.media.audio|video.update()` since it is called on Update and returns a `wp.shortcode` object now.
* In `wp.mce.View.render()`, fire a `ready` event when the placeholder is being parsed and pass the current node to the event handler.

UX Changes:
* Don't add a menu item for "Add Audio|Video Source"
* In the Audio|Video Details modal, add buttons and some suggestive text for adding alternate playback sources
* Don't show "Create Audio|Video Playlist" menu items until the user has uploaded audio or video files
