Subject: [PATCH] Fix swamp hut cat generation deadlock
The worldgen thread will attempt to get structure references
via the world's getChunkAt method, which is fine if the gen is
not cancelled - but if the chunk was unloaded, the call will block
indefinitely. Instead of using the world state, we use the already
supplied generatoraccess which will always have the chunk available.
