* 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.
