No Spawn Zone

Addon now prevents spawning of all mobs by default. You can exclude mobs with an excluding list. The excluding list contains a list of mobs ids, see /nsz listids.

e.g.:
/nsz create Village 100 35 100 200 36 200 {125,200}
In this case no mob will spawn in the defined area, except zombies (id=125) and friendly entities (id=200).
