Update uploader to rely less on the proxy
Add a new embed hook setting and fix edit dialog layout

Users got confused when the embed button was moved from media_buttons
to a tinymce plugin, this commit allows users to choose which one
should be used (or both)

Also fixed a minor layout issue with the edit dialog box.
Improve format detection and new upload dialog

The upload dialog has been made a lot more friendly. Instead of showing
a status update for progress we’re now showing a progress bar.

Formats now fall back to the file extension if we can’t look up the
mime type, also resolves a bug when a mime type wasn’t found.
Fix edit/upload template layout issues

The shared template for editing and uploading Media didn’t generate
valid HTML causing some issues with the layout.
Fixed width settings fields
Standardize our scripts/styles naming convention
Fix a bug when adding a shortcode in the text editor
Improve messaging during upload
Change our bootstrap theme
Fix upload form style
Upload changes
Uploader now uses session cookies correctly

This should finally fix spotty uploads, and have everything go through
WP Ajax proxy
Tidy up the uploads
UX Improvements to the media browser

We now only execute one ajax request at a time, so users who click
around on everything will only get one result set.

The media content pane now hides when no media is selected, and media
is unselected when there’s no available media in the view. Previously
this created a situation where users could update media that no longer
appeared in the list
