Wrap BlockInvoke() calls with a helper function that releases the GIL

Browse Source 
* This means that if we BlockInvoke a python callback, we don't end up
  in a deadlock where we're holding the GIL during script execution but
  also waiting on the renderer running (which is trying to acquire the
  GIL before calling the callback).
