Support the new MC 1.8 64x64 extended skin format. Adds on to the 64x32 skins with additional features. Most notably, new textures for left leg and left arm. Currently the left leg and left arm are textured from the mirror image of the right leg and right arm, but 64x64 skins let them be textured independently. 64x64 also adds more layers (like the hat GH-7 over the head), which are slightly above their parent mesh: jacket (body), rLeg2, lLeg2, rArm2, and lArm2.

Probably best to convert 64x32 skins to 64x64 on load, so the UV coordinates can always be consistent (box-geometry.js var tw = 64, th = 32 to th = 64)
