reverts Kolith's shotgun rework
Created by: SonixApache
for @yclatious / @aratherangryduck because he's too much of a lazy shitbag to do it himself and instead asks me to do it
Personally I think the rework is a mixed bag; I like some of the features, but I feel it's made shotguns even more tedious to use. I wouldn't mind the rework if we had CM's ammo pooling feature.
Tested.
