cuberite-2a/source/cServer.cpp
faketruth b5b920deda You can now run multiple worlds by defining them in settings.ini . However there's no way to change worlds on the fly yet 
Players are now stored in separate folder /players instead of in the world folder (!so move the folder!)
Fixed a memory leak/error in cPickup.cpp
Multiple worlds are stored in cRoot
cClientHandle lists are taken out of cWorld and now stored in cServer
Worlds now have names to distinguish them by
Some functions in the Core plugin now distinguish between worlds
