0.9.2 bug fixes, improved feel, easier difficulty

Fixes and changes:

-added a small squat to the start of throw (very subtle)
-decreased max shooting power, this should make the game a tiny bit easier
-keyboard controls should work without issues now
-the basketball texture is fixed (no more dark line in the middle)
-stats are shown for 2x time
-the "score!" texts in the background now take less time to update
