Determines what type of object this will be treated as when in the player's inventory (defaults to Junk). Junk is the behavior for crates, rubble etc. - centre of the lower screen, and the player cannot frob anything else until the object is dropped/removed. Item and Weapon are items the player can accumulate (lower right corner of screen) and weapons (lower left) respectively. Note that the actual behavior of objects when frobbed in inventory is determined by the Engine Features->FrobInfo property.
