Generate a more efficient terrain mesh #2

Currently, the terrain mesh is generated very naively and adds in many cube faces which are never visible. Instead, only draw cube faces which are exposed to air.
Merge voxel cubes in the mesh using using something like run-length encoding.

Terrain geometry generation now excludes faces which are not exposed to air.

Next steps: It would still be useful to merge adjacent voxel faces where possible. Also, using tristrips instead of trilists would reduce the amount of geometry that is actually rendered.

Reducing the amount of geometry with a more efficient mesh will also have a positive impact on the time to generate terrain and the time to generate chunk VBOs. I'm not sure how much of a win this would actually be, though...
