Fix relight and removelight (#475)

* Start work on lighting engine (does not build)

* Implement getLighting

* Setting, flushing light etc works. Getting light should be working..?

* Better queue/chunk handling

* Use correct location for lighting update

* Correct set location, remove debug

* cleanup a little

* Fix fixlight

* Apply to all versions for the numpties

* Remove lighting extent if not using

* Actually bitmask blocks when setting in chunks

* Initialise Maps and Dequeues with inital size

* format

* Documentation maybe
