NormalBlending is a bit better. But it's now producing some premultiplied-alpha-looking issues still :/

Created a couple of tools for making this process less painful:

Single quote property names and hex numbers are not valid in JSON.

For some reason Chrome canary 12.0.713.0 doesn't have "window.WebGLRenderingContext".

Also fixed multimaterial ids list.

Also changed AdditiveBlending.

Work-in-progress.

So close yet so far. Test scene almost works, just two things are not rotated properly (which means maybe everything will need to be reworked :(

- model loader now handles "wireframe" parameter

- scene light colors are now specified via hex numbers

- scene format now includes additional parameter "urlBaseType" specifying where loader will look for included files:
    - options are "relativeToHTML" (look for files under HTML url http://example.com/mydemo/index.html)
      and "relativeToScene" (look for files under url from where scene was loaded http://example.com/assets/myscene/scene.js)

Simplified JSONLoader.

Updated build script.

WebGLRenderer: Made material program sharing a bit simpler/efficient. API still not good for this, but works.

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Unfortunately C4D exporter is outdated and we don't use that.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)
