+ Fix btSubsimplexConvexCast

Browse Source 
Thanks to Nacho, http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2422)
Fix in rendering, GL_STENCIL
+ btTriangleIndexVertexArray indices should be unsigned int/unsigned short int,
+ Made InternalProcessAllTriangles virtual, thanks to 
Both thank to Fullmetalcoder, http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2401
+clamp impulse for btPoint2PointConstraint
Thanks to Martijn Reuvers, http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2418
+ Free memory of bvh, pass in scaling factor (optional)
