Updated builds and README.

(also fixed vertex colors to use proper per-face-vertex colors)

As now buffers are created based on first material that is encountered per shared Geometry, most complex material should go first.

Also updated docstring for OBJ converter.

All WebGL examples should now work.

Merging with alteredq's branch.

This one was messing up face types for faces with more than 4 vertices (which are truncated to quads).

Also some fixes along the way to properly handle vertex colors in loaders.

Many things still broken, but we move forward.

About to try to bring Face4 back.

Fixed some examples that used ParticleCircleMaterial.

Tons of things still broken.
