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.

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

Many-to-many mapping between settings and controls.
* Settings and controls have been separated in both the PHP (WP_Customize_Setting, WP_Customize_Control) and the JS (wp.customize.Setting, wp.customize.Control).
* While most settings are tied to a single control, some require multiple controls. The 'header_textcolor' control is a good example: to hide the header text, header_textcolor is set to 'blank'.
Add 'Display Header Text' control.
A handful of miscellaneous bugfixes along the way.
Notes:
* Controls should be separated out a bit more; juggling type-specific arguments in the switch statement is rather inelegant.
* Page dropdowns are currently inactive and need to be re-linked.
