[antifarm] Mobspawners, mobfalls and butcheries are now supporting exceptions lists. So you can define mob that will ignore antifarm settings.
[antichet] Some "freezer" optimization. It will be more efficient (I hope... )
[world] Now you can defined unsnowable biomes (prevent snow form in specified biomes).
[system] Added "lampdebug" mode. This mode will prevent all redstone lamp toggle and will be usefull when you using Worldedit to copy/paste redstone lamps. Don't forget to disable this mode, else it will break all redstone power actions in the server.
