Adding Custom Armor Textures

For now you just put in the vanilla assets, however we do have a utility for automatically creating the assets for armor trim item textures!

Under the [Rebar Item Definition] for an armor item piece, simply add "create_trims": "<piece>" to the definition.
- <piece> should be be one of helmet, chestplate, leggings, boots And the generator will automatically create the item assets for it.
