Openkore: Move inventory-related Actor::Item methods to a new class based on Actor::Item

[farrainbow]

Actor::InventoryItem (to keep the tree simple) or Actor::Item::InventoryItem.

I believe Actor::Item::Inventory and Actor::Item::Ground would be best.

@allanon @itsrachelfish @alisonrag What do you guys think?

[ghost]

I think a great idea @HenryBK but i think it need something to work as classes such as Map::Items;Map::Players;Map::NPC::Map::Portals;

According with responsability and creator design.
