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.
