Change blending method on shadow polygons. Updated example to use Lambert material and only one shadow casting directional light.

This one doesn't touch height, just centers model in X and Z axis.

This was messing models with mixed uv/non-uv faces.

Also bumped up version number for max exporter.

Updated GeometryUtils.merge with Face*.color changes.

Unfortunately C4D exporter is outdated and we don't use that. Removing it for now... Hopefully someone will re-port the Blender exporter again.

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).
