Support for Greedy Meshing for complex voxel worlds

[HeadClot]

Greedy meshing would allow complex voxel worlds have much less complicated geometry when adding and removing blocks. Example

Wouldn't work so well if smoothed voxel terrain were being used. However, the Dual Marching Cubes algorithm gets around that problem by using an octree to optimize the geometry.
