Consistently applying this setting requires some code work,
because Irrlicht does not provide a global toggle.
At the same time I don't see any reason for someone to disable this.
* Generalize mesh chunking. Set 3x3x3 chunks.
* Make mesh chunk size configurable... Default to 1 (off).
* Extract all mesh grid maths into a dedicated class

Reduce the number of drawcalls by generating a mesh per 8 blocks (2x2x2). Only blocks with even coordinates (lowest bit set to 0) will get a mesh.
Note: This also removes the old 'loops' algorithm for building the draw list, because it produces visual artifacts and cannot be made compatible with the approach of having a mesh for every 8th block without hurting performance.

This change removes a few (but not all) unused functions.
Some unused helper functions were not removed due to their complexity and potential of future use.
