Chunk system patch was refactored to take advantage of newer ConcurrentUtil's concurrent long hash table (which fixes hash collisions caused by chaining fastutil's long hash and CHM's hash) plus some other minor improvements. The chunk system was also merged with Starlight, which mostly provides a small improvement to ThreadedLevelLightEngine#checkBlock as the scheduling was rewritten.
