- Move configuration loading into a separate file, just so it doesn't
clutter up ComputerCraft.java.
- Normalise property names, so they're all snake_case.
- Split properties into separate categories (http, turtle, peripheral),
so the main one is less cluttered.
- Define an explicit ordering of each category.
- Convert most recipes to JSON
- Add JSON factories for impostor and turtle recipes.
- Several mappings changes
- Migrate to Forge's new registry system
Before we were setting the default as the previous value each time. Here
we store each property in a separate field, allowing us to access them
without setting a default.
