Support AVD Creation/Tear-Down and Target Modification

[JakeWharton]

Based on specified and provided device configurations. Automatically tear up/down AVDs and change settings like font size, orientation, locale, etc. across all devices.

Provide desktop Swing/JavaFX app to easily create and manage these configs. Should also allow running from this app for kicks.

Note: this depends on #4 being implemented.

I'd like to be able to compare the same screen with different languages (different locales)

In the mean time, I think you can turn on overdraw (and other things) reflectively in your test code similar to this example from Espresso.
