[Papervision3D] Model Viewer updates

[John Grden]

man that sounds sweet jake!  I'm guessing with the ability to load a zip in
at runtime and use it's assets, this would work out very well - no?

Also, right now, the ase importer maintains all of the object's
scale/rotation/position in the scene from whereever it was created even
though it's just the single item
