Inventories

Lets scripts identify inventory wrappers through the Inventories global,
instead of matching screen-name strings.

const inv = Player.openInventory();  
if (inv instanceof Inventories.Villager) {
 Chat.log(inv.getTrades());  
}

These names are available in JavaScript and Python without importing anything. They are read-only aliases of Java types, so instanceof works as usual.
