Load normals from the 3DXML file, added an option for using auto smooth.HEADmaster
Fixed random reference errors. Also fixed several brain farts. 3DXML files generated by Virtools seems to have normals randomly flipped to the other side. There might be some unspecified ordering issues with the vertices in each face. I'm currently using auto smoothing as a workaround.
