[Bf-python] Render

[Joseph Gilbert]

I thought it might be a good idea to get a render module built. Anyway I
know dunk you were working on something. Let me know if you got anywhere.
I was looking at code and at its most basic the render module would only
need to set variables to the global 'R' RE_render struct and it's sub struct
'r' which contains global rendering data. Then a few functions to open/close
the render window.
It looks like rendering could get complex with radiosity/yafray, etc. and
even set background images, world settings,etc + even setting variables
associated with the render window, however, something to simply set global
'R.r' variables and open/close the window + do_render would be a start :)
