BGE patch: Optimization of bullet adaptation layer - part 1.

First batch of optimizaton of the bullet adaptation layer in the BGE.
- remove circular motion state update.
- optimization of physic adaptation layer for bullet: bypass
  unecessary conversion of rotation matrix to quaternion and back.
- remove double updates during object replication.
