Removing some commented out CSS and JS. Removing all mention of tags,
which were commented out anyway and never really worked well. The Grid
View now takes over the Media Library, removing the list view
altogether.
Simpler CSS for the grid, anticipating the switch from a slider to
specific thumbnail sizes.
Removing another reference to filters and tags.
Removing the CSS for the Media List button, which no longer exists.
Removing some unused CSS for the item count, which doesn’t currently
exist. (Maybe one day.)
Removing the delete-related JS since it didn’t actually do anything.
Adding fixed sizes for the grid thumbnails.
Removing unused files

Removing the CSS and JS that added the Media Grid button in the Media
Library — it now defaults to the grid view. Removing the simple-slider
library since we now have preset sizes for thumbnails.
Adding some screenshots to the README.
Initial commit. New media workflow `manage`, based on select for now.
Image editing
Render content region appropriately for edit image state in Manage flow
Responsive parity with admin menu
Add small, medium, and large sizing options.

For now, this "works," but I'd like to revisit to review all the
use cases that Attachments views or Library controllers have a
custom `edge` set, and whether or not we should backwards compat
support them all, or make them flex as well.
Remove the toolbar within the Manage media frame.
Add a bulk edit mode.

Add an option to wp.media.view.AttachmentsBrowser `bulkEdit`,
which defaults to false. When set to true, conditionally create
a SelectionBulkEdit view when multiple items are selected.

Multiple delete now possible.
Fix batch deleting only deleting half of the models.
Update screenshots in readme
Improve the boolean check whether to bootstrap media grid or not.

This was interfering with uploads completing properly, and displaying
"upload did not complete" errors when anything was dragged into
the media grid.
Position the uploader window into the content section of the screen.

The admin menu needs to be able to overlap the content area for
flyout menus, but we want the uploader window takeover to cover
the entire screen. Without refactoring markup, this can serve
as a stop gap for now.
