BulletSim: reduce jitter in avatar velocity when walking or flying.
OpenSimulator is VERY sensitive to changes in avatar velocity and will send an avatar update message when velocity changes more than 0.001m/s. This significantly reduces the number of avatar update messages by smoothing the avatar velocity returned by Bullet.
