Implemented AmoriaPQ. Fixed an issue with ItemIdSortHandler where empty
vectors given to the sorting module would cause an exception thrown,
wiping players inventory items. Thanks to Vcoc, revamped shop data for
GMShop (shop id 1337). Mount quest for explorers now uses event script.
Fixed some bugs regarding dojo, updated drop data, minor tweaks on
Mystic Doors, added expeditions for Showa Manor, Zakum and Pink Bean,
smart search for item slots on quest/npc rewarding system, attempt on
boss HPbar to focus on player's current target, quests with selectable
rewards now hands the item correctly, after the first PQ instance next
ones are loaded more smoothly.
