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's external inventory
 * Party Cooler
 * Monkey
 * Niffler
 * Courier Flap (both the item and the effect)
 * Apollo's Phoenix
 * Festive Present
 * Sudarshana Chakra (effect)
 * Boomerang (effect)
 * BOOM-erang (effect)
 * Cocktail Shaker (only instantaneously before drinking)

General rules of non-player inventories:
 * Items in them have cooldowns/energy/Frozen turn counters tick down during Round Effects.
 * This does not apply to Party Cooler. It also does not apply to items in Magic Hat, which instead have these thing tick down during the Hat owner's Effects Phase.


 * Legendary Ring turn counters still tick down while in them; supposing the turn counter hits 0, it remains at 0, and the effect won't activate until the next Effects Phase the Ring spends in a player inventory.
 * If an item with a non-player inventory is itself inside a 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.
 * If a Horcrux is stored inside an item with a non-player inventory and that item is removed from the game, the Horcrux is also treated as being removed from the game, so Weakened Soul is given.
 * This does not apply to Squirrel as items aren't actually stored in the Squirrel itself.


 * If a Monkey or Courier Flap is copied, the items inside of the original will also be inside of the copy. (This has been verified as a bug.)
 * This does not apply to Party Cooler.
 * If a copy of a Monkey or Courier Flap is waiting to hatch from inside a Primed Clonegg 5000, an item inside of it still has its 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 because a copy of an item waiting to hatch from inside a Primed Clonegg 5000 would not even have its own cooldown tick down. (This is an extension of the bug in the above bullet point.)
