Camera decay

If you have our inventory, you can enable the decay option, this way you can use your camera in a more realistic way, and have your camera for a limited number of shots.

Config.DecayToUse = true    -- Only for qs-inventory, read above!
Config.DecayToUseRate = 1   -- Decay level due to use, the item has 100 durability, therefore 1 = 100 shots.
