lua rewrite boomshine
rewrite the logic of boomshine to make it more difficult especially small screens rewrite of the game engine to make memory usage more consistent throught the level and decrease overall memory usage this also removes most of the stuttering in play Add test of device speed this should improve very slow devices but the threshold might still need tweaked Change-Id: I49f5269c69405f6b6060ab18f52c96e3f69ebb14
