Max Ammo - Massive Backpack - Extremely slow Weapon degradation

This is for people who want just a large backpack. 100, 250, 350 size (100 is base and ups with perk upgrade). No other changes come with this.

Per user request this version comes with way less space (20 base, 50 on first perk, 100 on 2nd perk), but also retains the other features such as slow weapon degradation and max ammo carry
