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.

* Removes use of jquery.postmessage.js
* Fixes bug where Opera would attempt to use the hash transport and redirect to the dashboard.
* Fixes bug where multiple postMessage connections could not coexist in a single frame.

* 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.

* Use theme customizer in theme install/update screens.
* Separate the customize loader from the customizer. Use wp_customize_loader() to include the loader script and markup.
* Deprecated: wp-admin/js/theme-preview.js is now no longer used by core.

* Use event delegation for triggering the customize loader (so we play nicely with infinite scroll).
* Use data attributes on .load-customize links instead of parsing the href.
* Properly translate the 'Customize' string instead of injecting the replacement with JS.

* Replace the convoluted wp.customize.Value.link method with a simple shortcut for direct binding.
* Add wp.customize.Value.sync for bidirectional linking.
* Add wp.customize.Value.setter for handling compound values (instead of using wp.customize.Value.link).

Instead of grouping together every control parameter into a single array and passing them all to the JS, use subclasses with custom parameters to implement additional PHP functionality and the parameter to send only the necessary variables to the JavaScript control.
Replaces WP_Customize_Control->control_params with WP_Customize_Control->json and WP_Customize_Control->to_json(). The to_json() method refreshes the json array passed to the JavaScript control (set to control.param by default).
Creates WP_Customize_Upload_Control and WP_Customize_Image_Control.

This occurred because we weren't calling UploadControl.ready (where the actions are declared and the uploader is initialized) in ImageControl.ready.

This both better conforms to the CSS spec and prevents bugs from occurring in JavaScript selector engines.
