API8 and speed fix

This release should run on API8 (Android 2.2 Froyo) devices without any issue.
Further more the motion speed was fixed via deltaTime to be like the original ~15FPS version.
The lviewallpaper will still run at any framerate the onDraw is called with by the phone but motion is smoothed and slowed to the original ~15FPS version.

MALI GPU fix

With this version it now also runs on MALI GPU devices like Google Pixels and such.

Slight performance improvements

I got rid of the sleep to adjust frametimes as I falsely assumed I am not allowed to just outright return from the onDrawFrame function.
Some rearranging of OpenGL vertex attrib enables was also done to prevent them from impacting frame times as well.

Initial OpenGL ES2 release

This is phasebeam almost exactly as in the master at Android git.

Some bugfixes and performance optimizations have been made.
