Actors now have two types of slots: equip slots and wield slots.

Equip slots are what the player equips all gear into. Each slot
specifies how many pieces of gear it can hold; for example, a person can
have two pieces of gear on their back.

Wield slots are, for lack of a better description, the actor's
equivalent of a person's hands. Those hands can hold a sword, but that
sword still occupies its equip slot at the same time.
