Hired Merchant & Player shop fixes + Owl of Minerva

Thanks to BenjixD DietStory's dev team, many bugs found by them have
been patched (pirate quests, missing drop data, fly command, etc).
Implemented Owl of Minerva. Fixed many issues with Hired Merchant and
Player Shops. Fixed an error with the slot checking system. Added Wish
Tickets (circa-2006 GMS event) to be dropped on AmoriaPQ.
