Two small changes to help with the crafting system

First change: give players the option to scrap acquired weapons and curios for Plasteel. While I know that FatShark really put a lot of work into making resource gathering a big aspect of gameplay, there is always someone who is gonna want to speed-run missions for one reason or another. And this would also help those who are trying refill there Plasteel reserves with less grinding.

Second change: Alter the weapons vendors stores so that they always have at least one melee weapon and one ranged weapon available with a blessing you have not yet unlocked. Again this is directed at reducing the sheer amount of grinding needed for finding or creating your perfect weapon.
