* Fixed a bug in Object.getSelected(). All the objects were returned in stead

of just the selected object(s). This bug was pointed out by
  Jacek Poplawski.
* If there's already a PyObject of a certain object available, then don't
  create a new one, just return the specified object.
* Updated the Object_getData function to return correct objects. So far it can
  return objects of type Camera, Curve, Lamp and Object.
