Changelog for Release v1.2

Legacy4J Notes

Unfortunately seems like the Legacy4J mod uses the same container sprite for all of the UIs, so I can't give each container their own look so they won't have their unique color coded containers :(

Fixed

• Colored Shulker boxes now have an OptiGUI format as well as an Optifine format
