- Added mob_ai condition &16, enables skills that are normally used on 'friends' to also pick up caster as target.
- Fixed npc_shopid not being reset to 0 when buying/selling. FIXME: The client sends a packet when you cancel? It is required so that npc_shopid will be cleared and prevent the player from being stuck.
