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.

Fix import issue with Morrowind by basically rebuilding niflib correctly and rolling back a last minute change that I made after misinterpreting one of Shon's changes.

Added a staging area under Importer directory for the build intended to be submitted for a release.

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()
