 {{{
 #!CommitTicketReference repository="" revision="20645"
 Theme Customizer: Migrate to an ajax-based solution for refreshing the
 preview and saving. see #20507, #19910.

 * 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.
 }}}
