Store the context for python in a static variable with assessor functions - BPy_GetContext/BPy_SetContext,

Still not happy with this in the long term but its less problematic then storing the context in pythons namespace which couldn't be set before importing modules.

This might fix a crash quite a few people have reported (but I cant reproduce).
