Subject: BulletSim: fix density since the simulator/viewer track density in a
 funny unit that is 100 times real density (default 1000). Fix avatar drifting
 slowly when stationary flying. Fix for physical prims getting corrected for
 being under terrain when it was just its geometric center that was below
 terrain. Add PreUpdatePropertyAction allowing plugable modifiction of phys
 parameters returned from Bullet. Fix an exception setting GravityMultiplier
 on initialization. Update DLLs and SOs for good measure (no functional
 change).
