Improve logic node actor harvesting.

"Improve" is not quite the correct verbiage here because there were bugs
in the old code. The main issue is that any SceneObject with a
plPythonFileMod attached MUST have a CoordinateInterface attached,
otherwise the object would be invisible in game. Further, there were
some unreported oversights with regard to auto-generated modifiers that
have been fixed.
