* A bunch of updates to make things more smooth.

** Sending the actual TimeDilation to the client now instead of the 62455 constant.  The client is *supposed* to use that value to sync with the simulator.    (actually sending ushort.maxvalue * TimeDilation)
** Disabling prim that inter-penetrate instead of just not attaching a joint
** Reduced prim spin a 'little' bit, but not *enough* 
** Tweaked the TimeDilation algorithm to be closer to 1.0 by default and various changes to the sim stats reporter 
** Created a .SetValues method to PhysicsVector so we can simply call the setvalues function instead of .x, .y, .z sets.
** Experimented with a .GetBytes Method on PhysicsActor to be able to use the LLVector3.FromBytes() method.   
** Upped the Inter-penetration depth to 0.25 instead of .08.
