BuyableShotgunPlus

The shotgun and its ammo can now be purchased from the shop.
Since the shotgun is considered "scrap" you can resell it to get back some of what you spent.
This mod should ensure that both the shotgun and ammo are saved correctly when a save is loaded again.
The price of the shotgun and the ammo are configurable, but with limits (see in the config).
The configs are fully synced.
