BulletSim: experimental movement of physics execution off of heartbeat
...
thread. Off by default until more testing.
Setting "[BulletSim]UseSeparatePhysicsThread=true" causes the physics
engine to be called on its own thread and the heartbeat thread only
handles the reporting of property updates and collisions. Physics frame
rate is about right but physics execution time goes to zero as accounted
by the heartbeat loop.

BulletSim: apply friction to linear and angular motion before returning advanced motor value. This seems to be the problem with BulletSim vehicles turning too quickly.

BulletSim: fix vehicles going underground when unsat. Problem was that, when doing unsit, the order of operations on the prims and the vehicle is very chaotic and not in a good order so the root prim was being left physical and thus it fell for a bit. Also changed default of velocity scaling to be closer to the movement standard.

BulletSim: add ini file and command line parameters to control

dumping of physical vehicle parameters (out of Bullet) on each
simulation step and to optionally scale vehicle angular velocity
by the time step. The latter looks to be part of a difference
between angular parameters for ODE and BulletSim. SL docs say
angular velocity is measured in radians/timeScale. Not sure if this
is different than what ODE does.
