Fix World#isChunkGenerated calls (#2186)

Browse Source 
* Fix World#isChunkGenerated calls

Optimize World#loadChunk() too
This patch also adds a chunk status cache on region files (note that
its only purpose is to cache the status on DISK)

* Ensure correct regionfile usage

This also bumps the minimum region file cache to 4 files given
readChunkData can load potentially 4 files.

* Fix closed check

* Better checks for invalid regionfile usage
