Moved the fast select GUI to nine patches.

Luckily, no one ever used it anyway.

 Components
 ==========

 A theme is made up of components, which have various types. At the moment, the only type is `image`. Components are rendered in the order they are defined - that means you'll want to define the background first, a header image second, etc.

+Nine Patches
+============
+
+EmulationStation borrows the concept of "nine patches" from Android (or "9-Slices"). Currently the implementation is very simple and hard-coded to only use 48x48px images (16x16px for each "patch"). Check the `data/resources` directory for some examples (button.png, frame.png).
