Ambient occlusion baker from multi-resolution mesh

This implements AO baking directly from multi-resolution mesh with much
less memory overhead than regular baker.

Uses rays distribution implementation from Morten Mikkelsen, raycast
is based on RayObject also used by Blender Internal.

Works in single-thread yet, multi-threading would be implemented later.
