[#18802] BGE conversion script: more attributes; updated GameTypes.py
Patch from Alex Fraser (z0r)

- All attributes in the conversion map have been checked against the docs. More ambiguities have been resolved.
- Added option to convert all text buffers in Blender.
- Updated GameTypes.py: there were inconsistencies.

The script works well (causes no errors) with 0_FPS_Template.blend and vehicle_demo.blend from the
physics-2.43-physics-testfiles pack.

Caveats:
- Conversions were checked against other deprecated attributes. I may have missed some cases where a deprecated attribute
has the same name as a non-deprecated attribute. I did catch a few though.
- As with the last version, the conversion is purely text-based and doesn't compile the code. It's easy to create a
script that would break on conversion.

Still, it should get you 90% of the way to a converted script.
