Customizer: Improve `ColorControl`'s `wpColorPicker` to update UI based on setting changes.

Update Twenty Fifteen's `colorScheme` control to properly interact with the API, using `wp.customize.control()` instead of traversing DOM for other controls' container elements and stop manually updating color control UIs.

Revisions modules should not rely on global settings:

* Only pass in global settings on `init`, this allows the classes to be used agnostically elsewhere
* Clean up some erroneous/weird Backbone syntax

This encodes them, adds unit test.
