Subject: [PATCH] improve CraftWorld#isChunkLoaded
getChunkAt will request the chunk using vanillas chunk loading system,
which while we're not going to load the chunk, does involve the server
waiting for the execution queue to get to our request; We can just query
the chunk status and get a response now, vs having to wait
