Greyson Parrelli 8f551c8b32 Fix various redesign issues with Android 4.x.
In particular, there were many issues with drawing corners.
Unfortunately, there's no pretty way to get masking working on every
Android version, so we have to switch back to using custom backgrounds
and then using multiple masking methods depending on Android version.

Also, I had to remove attr references in drawables. They crash on 4.x.
