NiPacked nifs export.
Beginning conversion to poly/loops import method
Faces import as polygons, loops
Polygons, loops import with uvmap and textures applied. Merging vetices
during import is now supported.
Vertex colors import and support vertices merging.
Repositioned several dictionary variable so they reset as intended
during import and export.
Final cleanup for pull
Small edit to polygon import, combined mesh import now works, uvmap
import is next to be updated accordingly
UV maps are applied to meshes, combined import now fully functional
Optimize UV assignment so that it only runs once per texture.
Merge pull request #142 from Ghostwalker71/import/poly

with class vs method level setup.
Removed duplicate imports
Tidied up the matrix test, still needs to have correct matrix building
