When describing items in the inventory, both in detail and when producing menus from those items, describe not just the item itself but also *where* in the inventory the item is (either in the backpack, or wielded in either or both of the hands). This uses a new InventoryPosition datatype, and a method to get a list of items in the inventory associated with their inventory position. When *removing* items from the inventory (to wield, drop, or eat them), we want to make sure we remove from the right position, so this also introduces a `removeItemAtPosition` method to make that happen correctly. Finally, some of the tests for this stuff was getting really slow - I narrowed this down to runaway arbitrary generation for message Templates, so I've tweaked the Arbitrary instance for that type to generate smaller values.
