OBJ exporter working (Python 3.0), but needs testing and fixing.

Current issues:
- NURBS - needs API additions
- "all scenes" export - cannot switch scene in bpy
- normal calculation, disabled
- duplis - need testing, only dupliverts tested
- matrix problem
- UI, 18 options currently don't fit into filesel panel, will do manual lay out once it's available
- probably others...

BPY:
- made operator "execute" method required to avoid crash
- added bpy.sys module which replicates old "sys" module

API:
- replaced create_*_mesh with a single create_mesh accepting type parameter
- added Mesh.create_copy to create a copy of a mesh with 0 users
