BGE Py API

- setting the scene attributes would always add to the scenes custom dictionary.
- new CListValue method from_id(id)

so you can store a Game Objects id and use it to get the game object back.

 ob_id = id(gameOb)
 ...
 gameOb = scene.objects.from_id(ob_id)
 
This is useful because names are not always unique.
