Json Things

Bump to latest forge 1.20.1. Add the ability for item types to provide variants for creative mode tab purposes. This is used when listing a builder by name in a creative mode tab json (as a resource location string), and when specifying "group" in the item json. Add before/after dependency arrays to creative mode tab jsons. Add "right_side" to the creative mode tab jsons, so they can choose their preferred alignment.
