Add mod support by uploading mod jars or some other way

Add the ability to upload mod jars to be able to use in modded environments with new types of crafting

Sure although not all the data is accessible just in the .jar, at the moment I can pull all items and recipe data from the jar --but not entities and blocks (for vanilla I webscrape these from a opensource de-compiled mc code repo and Mojang's manifest), meaning I couldn't add the same level of support as vanilla.
