[Suggestion] Add Spawn blockers

As of this moment it does not seem like players, buildings or anything has a spawn blocker for creatures. Players should have a roughly 20 building square spawn blocker in all directions. And buildings should have something like 50. Having a bear or wolf spawn literally next to you is extremely obnoxious. It doesn't bother me to have deer and goat and what not but aggressive mobs need to not spawn right next to us.
