Gryphon wings mesh

Made a more rigging friendly version of the wings that still keeps most of the appearance of the other style.  I'm a little over my previous goal for poly count, but the texture still works at 1024x1024 for the entire model, so I think he's doing pretty well on memory usage.  I'll go back over him and see what edges I can remove to try and bring him back down to around 3k anyway, though.
