Refactors like all of forge code, improves the functionality of using it like an oven, these two items are unrelated

About The Pull Request

What the players see:

The forge upgrades system has been reworked to be fully based upon what your forging skill is, rather than giving a forge random lavaland loot. As a part of this, there are forge upgrades for every level of forging skill, rather than every two levels.

What the players don't see: (Just imagine there's a giant wall of code screenshots here)

How This Contributes To The Skyrat Roleplay Experience

Makes baking using forges a bit more practical, makes forge code more practical, also a bit cooler. I write this mere moments before I go to sleep so forgive me for not being super creative with this one.
