[Bf-python] GameEngine GetGameObject() Patch

[maci_ray]

First posted to bf-committers list...

Hi Blenders,

attached a little patch, which enables a method GetGameObject()
in GameLogic module. It has the same functionality as the Object.Get()
Method from ExpPython.

Please check and commit if you like it.
