Added a /cosmetics Menu! Access all wearable cosmetics and assign players cosmetics via permission (advancedmodels.cosmetic.name), configuration: `AdvancedModels/menus/cosmeticsMenu.yml`
Completely reworked model naming - now names depend on groups (main folders). This allows having more than 1 model named the same. E.g. furniture:chair and outdoor:chair, first part being the group folder and second model name.
Previously placed models or cosmetics, as well as inventory items will be auto converted and work fine.
