Added Map.SetChunkSize. Can now have custom sized chunks. Removed all static references to Chunk.VoxelSize and Chunk.ChunkSize. Various optimizations. Added Map.SetChunkRenderDistance and Map.SetChunkUnloadDistance. Added Map.SetMinimumLoadedChunks. Now update light map on both client and server, but only perform the initial update on server and send it to clients with a chunk's initial data.
