We ran into an issue where our players set up chicken farms to rapidly gain experience with no danger to themselves. We didn't want to have to redefine or override all of the item drops for every mob just to nerf the experience dropped by chickens, cows, etc. Pulling this out lets us keep vanilla drops, while overriding Experience drops per mob (and expmin/max/percent out leaves it at vanilla exp).
