cuberite-2a/source/cWorld.cpp
faketruth 01398f8424 Fixed the numchunks console command. 
Added some form of reference counting to cChunk to make sure it's not referenced when deleting it.
Right now it's only needed due to the generation of chunks in a separate thread and adding it to the spread light list in cWorld
