bebe12d6d8 tweak tensorflow humanoid_running.py demo to be more robust against mouse dragging 
(mouse dragging adds energy in the system that can cause explosions/instability):
use solverResidualThreshold and increase number of sub steps, also clamp the max force.

a44df2b0a6 PyBullet: allow to pass vertices (for convex) and vertices+indices (for concave) to createCollisionShape 
See createObstacleCourse.py for an example use. At the moment a limit of 1024 vertices and 1024 indices.
Will be lifted once we implement the streaming version (soon).
