Subject: [PATCH] Entity Activation Range# This feature gives 3 new
configurable ranges that if an entity of the matching type is outside of this
radius of any player, will tick at 5% of its normal rate.
This will drastically cut down on tick timings for entities that are not in range of a user to actually be "used".
This change can have dramatic impact on gameplay if configured too low. Balance according to your servers desired gameplay.
