Fixed pet Snail not expiring properly (being removed from inventory when the time's up).
Broadcasted code update for most of the missing portal sound effects for portal scripts. It is expected for all scripted portals now to play the sound effect when traversing it.
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.
