`figcaption` should not be treated as a block-level element by `wpautop()`. See #25646. Props oso96_2000.

Add MCE Views for audio and video. Please clear your browser cache so that you get the latest TinyMCE stylesheet.

* Move TinyMCE shortcode handling from `wpgallery` plugin to `mce-view.js`
* Force `preload="none"` when rendering media in the editor to ensure fast loading (I realize this sounds illogical)
* Move audio and video tag builder logic in `media-template.php` into PHP funcs that can be reused by any code passing `data.model` to an Underscore template
* Pause all players when moving between editor tabs and when moving from the editor to editing in the media modal.
* Rename `wp.media.audio|video.shortcode()` to the more appropriate `wp.media.audio|video.update()` that now returns a `wp.shortcode` object instead of a string.
* Add necessary MediaElement css files to `$mce_css`
* In `wp.mce.View.render()`, support multiple instances of the same shortcode
* When rendering `wp.mce.View`s, fire a ready event that passes the current MCE View root element as context 

See #27389.

Revert [27528] until Flash in Firefox behaves :(

Drag/drop upload: don't trigger on "local" dragging, hide the overlay on click. Props kovshenin, fixes #19845

Modals: darken all overlays, update all box-shadows and headings, correct thickbox styling, make the link modal narrower and bring back the animation (css transition). Props avryl, see #26952

When rendering Underscore templates for Audio/Video details, use 2 new PHP functions to render the markup for audio and video tags: `wp_underscore_audio_template()` and `wp_underscore_video_template()`.

Future JS templates can follow the convention of expecting `data` to be passed to them containing a `model` property.

See #27389.

Load MediaElement's CSS when TinyMCE is loaded via `$mce_css` in `editor_settings()`. Add some baseline styles in `wp-content.css` for audio, video, and embed tags to ensure their `max-width` is `100%`, regardless of whether MEjs is implemented in TinyMCE.

See #27389.



git-svn-id: https://develop.svn.wordpress.org/trunk@27534 602fd350-edb4-49c9-b593-d223f7449a82
Make `media.view.VideoDetails.prepareSrc` a static class method instead of an instance method. Properly pairs it with its incrementing `instances` property.

See #27389.

In `media.model.PostMedia`, for these 2 scenarios:

* `src` is set, and 'Add a Source' results in the same file (or a file with the same extension) being added
* `src` is set, and 'Replace Audio|Video' is used, which will add a model property named by the attachment's extension

... call `model.unset( 'src' )`.

See #27389.

Rather than extending `wp.media.mixin`, only borrow `coerce` when necessary in `wp.media.audio|video|collection`. `wp.media.mixin` will make sense to be mixed in for classes that expect to interact with the player. More universal methods can be added and inherited by all those who extend their prototype with it.

Assuming someone had implemented players in the editor, pause all players when switching between editor tabs. A method, `pauseAllPlayers`, has been added to `wp.media.mixin`.

See #27389.



git-svn-id: https://develop.svn.wordpress.org/trunk@27537 602fd350-edb4-49c9-b593-d223f7449a82
Move `removePlayer()` and `unsetPlayer()` to `wp.media.mixin` so that other classes can take advantage of them. 

* `removePlayer()` is an alternative to MediaElement's player removal method that does not re-add the audio|video element back to the DOM.
* `unsetPlayer()` will check for an existing `player` property on the passed instance and pause all players before calling `unsetPlayer()`

See #27389.

The `canPlayType` property for audio and video in JS is so bad that the official valid responses are "probably" and "maybe". There are many cases where we might want to know if an audio|video tag is gonna blow up in our face before even attempting to make a `MediaElementPlayer` instance out of it.

The best (and most cautious) way to tackle this is to whitelist types by browser. Imagine that one implemented MEjs in TinyMCE's rich editor mode, this would be very helpful.

Add `isCompatible( $media )` to `wp.media.mixin`. Future features will use this.

See #27389.
