Enhanced map bounds + HolidayPQ + Battleship

Fixed Abdula not showing book info for Arans.
Fixed map bounds, now it hopefully doesn't let items pass through the walkable area anymore.
Implemented HolidayPQ.
Added a custom item sandbox system, to be used with items generated by the "drop" command.
Added the whole-map buff when using the Happy Birthday item.
Fixed several battleship issues:
 - Battleship now shows HP properly at the buff icon.
 - Cleared some inconsistencies on battleship when interacting with the enhanced buff system.
 - Battleship now hands out defensive buffs properly.
