Create WP_Customize_Control to separate the process of rendering a control from fetching, previewing, and saving its values. see #19910.

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.

Theme Customizer: Sanitize selectors by transforming square brackets into dashes. see #19910. 

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

Theme Customizer: Properly pass arguments by reference to WP_Customize_Setting->multidimensional(). see #19910, [20136], #20163.

This is necessary for WP_Customize_Setting->multidimensional_replace() to work properly on multidimensional arrays (which was, as the name indicates, the point of the function in the first place).

Theme Customizer: Properly bind the 'upload new' and 'remove image' actions in the image picker. see #19910.

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

Theme Customizer: Fire WP_Customize->customize_preview_init on wp_loaded instead of template_redirect. props nacin, see #19910.

Certain customize settings (such as show_on_front and other static front page features) need to be overridden before template_redirect.
