3. Civ4 Shader support for max
4. Numerous bug fixes to max.

  - Added Vertex Color modifier support

  - Fixed issue with skin vertex weight count import
  
o Exporter
  - Dropped registry support in favor of INI file.
  - Dropped Official Max6 support because I do not have SDK to compile it with (try the max 7 files).
  - Fixed issue with importing glossiness setting on textures.
  - Fixed issues with export of vertex color. Alpha map is now exported as part of the normal color map.
  - No longer exports meshes associated with bone or biped nodes.
  - No longer exports extra NiNode when exporting NiTriGeom-based objects (can be reset in ini file)
  - Mass, Restitution(Ellasticity), and Friction now share values with Reactor(Havok)
  - Modified UPB export to actually export the values in the UserPropBuffer not just a fixed list.
  - Added Skin Modifier export
  
o NifProps Utility
  - Mass, Restitution(Ellasticity), and Friction now share values with Reactor(Havok)

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

Add some new options to better auto-detect where the imported nif is coming from and default to correct application based on root paths.  Also add some assistance for locating skeleton.nif files if needed.

Add options to force nubs to point back to parent node at the expense of the rotation data.  It looks better. Need to alter the zAxis instead I think.

2. Fix bug with matrix inversion missing.  
3. Use Point3(0,0,0) instead of Point3()
