FF - Shop Overhaul WIP

* * Work in Progress — Features and balance may change. Full functionality not guaranteed.  * *

This mod connects Freedom Fighters to Shop System by ekudmada. I love Freedom Fighters, but the vanilla shop UI has always felt clunky to me. Since I enjoy ekudmada's UI, I set out to integrate it into Freedom Fighters to replace the vanilla shop UI, with some functionality changes.

Additionally, this mod allows for the full customization of shops within Freedom Fighters through config files, without having to rely on premade integrations.

Config files can be found in your server profile folder inside of a folder titled "FFShopOverhaul". FobArmory.json has a working example for syntax.

- Allows for customization of shop inventories.
- Shows your current money or supplies balance in the shop.
- Highlights items that fit the actively held weapon.
- Gives clear error messages through FF notifications.
- Drops purchased items on the ground if your inventory is full.
