BulletSim: clean up TODO list. It is kept somewhere wlse that should be more public. Add error logging for the detail log writer so a message is output when it cannot write to the specified logging directory. Modify friction defaults to be closer to ODE's values. Add new collision margin and vehicle angular damping parameters.
