Subject: 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.
