Revises the concept of the media controller and workspace views (i.e. two central points of control) to be more granular. The main media object is now the `Frame`, which is a hybrid view and state machine.
The state machine is a collection of states, which are just generic instances of `Backbone.Model`. This circumvents the problem of juggling global parameters when changing states. Each state contains its own event loop. All events are also forwarded to the frame itself (as is the case in all model/collection relationships).
The frame view contains several regions, each of which can be overridden without harming or re-rendering the other regions. These work well when used in conjunction with the state machine events.
This removes the upload sidebar (don't worry, visible upload UI will return). Drag and drop uploading still works. The ability to upload has been abstracted into its own view (instead of being attached to the central workspace view).
Editing galleries is temporarily broken — the gallery creation and editing experiences will be unified in a future patch.
Adds events to detect dragging changes in `wp.Uploader` and adds methods to detect and leverage browser support for CSS3 transitions.

Moves the uploading Attachments queue from the media workspace view to the uploader itself. This ensures that all attachments are added to the central attachmnet store.
Updates wp.Uploader to pass Attachment models to callbacks instead of Plupload file objects. Attachments in the process of uploading have a reference to the file object (which can be fetched by calling `attachment.get('file');`).
Also updates the customizer to be compatible with the API changes.

* This moves our "development" versions from .dev.js to .js (same for css).
* The compressed version then moves from .js to .min.js (same for css).
By switching to the standard .min convention, it sets expectations for developers,
and works nicely with existing tools such as ack.

wp.Uploader is a wrapper that provides a simple way to upload an attachment (using the wp_ajax_upload_attachment handler). It is intentionally decoupled from the UI. When an upload succeeds, it will receive the attachment information (id, url, meta, etc) as a JSON response. If the upload fails, the wrapper handles both WordPress and plupload errors through a single handler.
As todos, we should add drag classes for the uploader dropzone and account for the rough 100mb filesize limit in most browsers. The UI for the customizer upload controls could be improved as well.
