New Collapse radiosity to Vertex Colors Script

Collapse radiosity to Vertex Colors Script.

What it does:
- grabs the meshing from the radiosity engine along with the lighting data for each vertex
- replaces the existing object mesh, modifiers, etc with a collapsed Editable mesh object
- assigns a shell material moving assigning a Vertex Color map to the Renderable material (optional)
- Operates on selection or the entire scene

What it does not do:
- use diffusemap color information or anything that's not part of the radiosity information
- Split direct or indirect lighting, allow you to turn on/off shadows

It has only been lightly tested, so please report issues if you see any and I'll fix them as soon as I can.
