Non-player inventories

Non-player inventories are places where items can be stored without being inside of a player inventory.

The non-player inventories are inside of the following:
 * Pawn Shop
 * Magic Hat
 * Squirrel
 * Party Cooler
 * Monkey
 * Courier Flap (both the item and the effect)
 * Apollo's Phoenix
 * Festive Present
 * Sudarshana Chakra (effect)
 * Boomerang (effect)
 * BOOM-erang (effect)

General rules of non-player inventories:
 * Items in them have cooldowns/energy/Frozen turn counters tick down during Round Effects.
 * Seventh Ring Of Hell's turn counter still ticks down while in them; supposing the turn counter hits 0, the generation won't activate, and the turn counter remains at 0, to be activated in the first Effects Phase after it is removed from the Squirrel.
 * If an item with a non-player inventory is copied, the items inside of the original will also be inside of the copy.
 * If a copy of an item with a non-player inventory is waiting to hatch from inside a Primed Clonegg 5000, or if such an item is itself inside a different non-player inventory, items inside of it still have their cooldowns/energy/Frozen turn counters tick down during Round Effects, and a Seventh Ring Of Hell inside will have its turn counter tick down. This is particularly interesting for the Clonegg because a copy of an item waiting to hatch from inside a Primed Clonegg 5000 would not even have its own cooldown tick down.
