Server now generates and sends an expanded 34x34 heightmap for each chunk, which includes a 1-vertex border containing height information from all adjacent chunks. Client ChunkMesh class updated to consume this extra data, allowing it to calcualte perfectly accurate normal vectors for all vertices, including those at the very edge of a chunk.
