Unfuck fireaxe cabinets

- Name changed to lowercase
- All messages to span, formatting and absolute pathing
- Fix cabinet so that ghosts can't fuck with it anymore use attack_AI
- The fireaxe now drops when the cabinet is destroyed completely with it still inside
- Small modification to fireaxe (absolute pathing)

Intended to fix the following issues (#2113 and #2108) and unfuck Erro's code in general
