Fixed rotation issue with animation import
Added biped "support" for max 7 (still cannot test properly but it compiles.)

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.
