1.3.0 Dynamic items

• completely reworked what you need to create gear
  • only a box collider, generic item component, and optionally stackable behaviour is needed. things like scale of said box collider, weight of item, or the box and items inside it will be set in runtime
  • expanded config file to facilitate that change. Not much is hardcoded.
• localisation is copied from single items, and inventory icons are mostly generic
• added submod with boxes for most FoodPackByTKG items
