exoskeleton upgrade

At the moment i am unable to add player upgrades. So made it so you can change the number of hand slots in the mod options.
This way you can pretend there is an item and when you make it you can change number of hand slots in the mod options, or you can just cheat and max it out. Your choice.
They are working on adding a player upgrade to solve this problem
