processed a lot of feedback: added 'realtime' simulation with fixed substeps (and clamping maximum number of substeps), this means that when stepSimulation is called with smaller timesteps then 'fixed substep' the motionstate is interpolated.

renamed m_ccdSweptSphereRadius,
enabled wireframe debugDrawObject (using debugDrawer)
