Save and Load Inventories

A big backend update!
Forge and Fabric (and Quilt) are now contained in one file.

This also means that the two separate project pages for Forge/Fabric will be converted to one (on CurseForge). While having a clean file list! The Fabric project page on CF will remain as a legacy for older Fabric versions.
