* Use a `MutationObserver` to listen to the `body` class of the parent editor frame.
* In `wpview_media_sandbox_styles()`, only return the MEjs stylesheets.
* In `wp_ajax_parse_media_shortcode()` and `wp_ajax_parse_embed()`, return an object instead of an HTML blob to allow passing `body` and `head` separately

- Make them transparent.
- Don't load tons of unrelated styles that can break them. This could result in minimal styling mismatch to the front-end, but keeps the views working well and looking good.

* `_WP_Editors::editor_settings()` no longer needs to load MEjs styles
* Make sure each identical shortcode with multiple instances also has an iframe sandbox for each instance
* For the time being, make audio and video shortcodes bypass the loading placeholder to avoid whiplash visually

Wins:
* Eliminates duplication of code between PHP and JS
* Views can load JS without messing with TinyMCE and scope
* MEjs doesn't break when it loads a file plugin-mode. This allows any file type the MEjs supports to play in MCE views.
* YouTube now works as the source for video.
* Users can still style the views, editor stylesheets are included in these sandboxes.
* Audio and Video URLs and `[embed]`s are no longer broken.
* Remove the crazy compat code necessary to determine what file types play in what browser.
* Remove unneeded Underscore templates.
* Remove the compat code for playlists.

- Add loadingPlaceholder() that returns some html to use as placeholder while the view is loading. Includes a subtle CSS based loading animation.
- Fix setContent(), it should empty the element before appending the new node.
- Change getHtml() to always return a string.

- Don't wrap single-line URLs in [embed]. Use them directly in generating a view.
- If the embedding HTML contains a script, "sandbox" it in an iframe to prevent it from changing the editor DOM.
- Automatically add toolbar and overlay when needed.
- Try to embed single-line URLs only if they are pasted in an empty paragraph.

* Rename the `wp.mce.media` mixin (which was named too ambiguously) to `wp.mce.av`.
* Use the same technique for extending mixins for MCE base classes for views and their base.View property class
* `wp.mce.views.register()` should have default constructor logic if one is not passed.

* When generating the view's HTML, ensure that the shortcode's `content` is added to the model
* Add a `PostProcess` event in the `wpview` plugin to properly return the shortcode when the editor mode is toggled, ensuring that elements in the body are not dropped.

* Add `visibility: hidden` as an inline style to `<audio>` tags, there is a race with the stylesheet which can get enqueued in the body and loaded in the footer.
* When creating new instances of `MediaElementPlayer`, always push them onto a stack. Lone views can be responsible for multiple instances of the same shortcode on render.
* Rename `wp.media.mixin.unsetPlayer()` to `wp.media.mixin.unsetPlayers()` to reflect the above.
* Call `wp.media.mixin.unsetPlayers()` on the view's `unbind()` method, instead of inline in the `render()` method
* Make sure `WPPlaylistView` is instantiated for each editor instance
* Ensure that the `No Items Found` view state is not rendered when attachments actually do exist.

- Prevent undo steps from being added when the body of a wpview changes.
- Add unbind() to handle cleanup on DOM rebuilding in TinyMCE.
- Ensure that MediaElement's cleanup routine is run on every player in all instances of the editor.
- Initialize the players after some delay to ensure CSS is loaded.
