About The Pull Request

Adds the 357 and shotgun lever actions, pending names and descriptions by apogee and sprites. A draft until those are completed.

Why It's Good For The Game

Upgrades to the .38 lever action rifle that provide a nice variety, with the lever-action shotgun being an inbetween of a double-barrel and pump action shotgun and the 357 being more expensive and with a smaller ammo capacity but with a lot more power.
