BGE : Fix crash during physics mesh update.

Currently we can't update the physics mesh of an added rigid body.
The cause is that that we need to update all shapes to say that the mesh was changed, for static object we don't do that previously because we use a odd way to reallocate memory at the same place.
So now when a mesh is changed we iterate all physics controllers which use the same shape info and recreate its shape with the correct mesh.
