free memory for btShapeHulls, keep track of it in GL_ShapeDrawer.

Browse Source 
move btShapeHull and btConvexHull into its own library in Extras/ConvexHull (it allocates memory using mem/delete and refactoring into using btAlignedAlloc/Free takes too much time)
fix heightfield / btOptimizedBvh for quantization, so that raycast can use quantized aabb (clamp up for maxima and down for minima)

work-in-progress (update projectfiles etc)
