1. Fix issue with exporting with user version specified.  Oblivion CS will crash if not set correctly.
2. Fix issues with nif export in general around bhk ordering (ported over from gundalfs changes)
3. Civ4 Shader support for max
4. Numerous bug fixes to max.

Commit Max 7 (ie no biped) changes since I have an old max7 demo floating around and can use the sdk off that cd to build.

Added initial animation support for embedded NIF controller data.  External files are suspect at the moment.
