hello,

attached is my patch which adds some python call back code. it will store a python function with Blender.CallbackFrameChange(myfunc) and run that func everytime the frame changes. i shall be looking to implement more functions like thia. 

this is my first patch so please be critical so i may do better next time ;)

i am also working on a render module that allows python to start the render process but this i shall look at again before submitting anything.

have fun
