Cleaned up Map and the Octree. Did some testing and refactoring of generation code. Interleaved data is now good, also changed the block stack dealio to just a blob of uint64_t data. Used a GCC and by extension MSVC extension which speeds up count_bits by a good bit. After all optimizations, getVoxel is now around 10-15 times faster.
