Add python exporter that exports a mesh in a C file in a renderer-ready
format (vertices + normals + triangle vertex indices)
This will allow us to create widgets in blender instead of defining them
programmatically.
May also support facegroups for different colors in the future though
they must be somehow tied to the UI colors.
