correction of an error where defense against cutting damage on armor was missing.

Optimization:
Basically I reduced the amount of faces contained in the models, from having 77000 to 13000, as a reference the vanilla robot model in the game has 10000 faces so this would have to be a considerable improvement in performance or at least that's what I checked, it should improve the loading time of the game and games.

I made some changes so that the armors were not so broken, since easily an unskilled character wearing the armors could reach level 60 without having skill
removed some extra squads that flooded some locations, leaving no place for the vanilla npc's in the game.
I also added the armors to be sold by tech hunter vendors.
