Jsonizes material reinforcing potential

[Ilysen]

Summary

SUMMARY: Infrastructure "The ability to reinforce a material is now tied to json."

Purpose of change

After playing with the inability to reinforce hard materials, I've since gotten over the fact that it's not actually that bad, but I do think that jsonizing where appropriate is always better than C++ hardcoding. (Considering jsonizing sleep comfort for furniture next...)

Describe the solution

Adds a new json field called reinforces to materials, which is enabled for Cotton, Leather, and Wool by default. I replaced the hardcoded checks for cotton, wool, and leather in reinforcing items for a call of a new function on item called reinforces() that checks if a material can be reinforced in the item's construction, and allows reinforcement if one exists.

This makes it easier for mods to edit existing materials, and much easier for adding new cloth materials down the line (for instance, if someone wants to add a Silk material, they don't have to worry about editing C++ to do that.)

Also added a notice that an item can be reinforced in its description, since it's no longer the norm for most clothing and armor in the game.
