* Use ajax-based saving, add saving indicator.
* Use ajax-based refreshing instead of form targets.
* Instead of using hidden inputs with prefixed names to track the canonical data, use the values stored in wp.customize. Encode the values as JSON before sending to avoid bugs with ids that contain square brackets (PHP mangles POST values with nested brackets).
* Use wp.customize.Previewer solely for the purpose of previewing; move the postMessage connection with the parent frame and other unrelated code snippets into the 'ready' handler.

Overhauled image pickers:
* Add support for drag and drop uploads to image controls.
* Improve the 'uploaded' tab in image controls: automatically add images uploaded during the current session, hide the tab when no uploaded images exist.
* Move the header image control to the WP_Customize_Header_Image_Control class. Remove wp_customize_print_uploaded_headers() and wp_customize_print_uploaded_headers() functions.
* Abstract the dropdown functionality from the color picker to the .dropdown class.
* In wp.Uploader, unset element keys if passed an empty jQuery collection.

* Move the 'Return to Manage Themes' and 'Collapse Sidebar' actions from themes.php to customize-controls.php.
* Create a postMessage connection between themes.php and customize-controls.php.
* Allow the theme customizer to be accessed directly (independent of themes.php and the customize loader).
* Add wp_customize_href() and wp_customize_url().
* Remove wp_customize_loader(). To include the loader, use wp_enqueue_script( 'customize-loader' ).
* The theme customizer now requires postMessage browser support.
* Add .hide-if-customize and .hide-if-no-customize CSS classes.
* Clean up customize-preview.js.
