Added 'cosmetics.limit-per-player' setting to limit number of cosmetic models per player (for Hats Pack https://advancedplugins.net/item/15-Hats-Pack.198)
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.
