=================================================
Redo BulletSimAPI to allow native C# implementation of Bullet option.
Avatar movement
flying into a wall doesn't stop avatar who keeps appearing to move through the obsticle
flying into a wall doesn't stop avatar who keeps appearing to move through the obstacle
walking up stairs is not calibrated correctly (stairs out of Kepler cabin)
avatar capsule rotation completed
llMoveToTarget
Enable vehicle border crossings (at least as poorly as ODE)
Terrain skirts
Avatar created in previous region and not new region when crossing border
