Used by the routines at Action_Examine, Action_Take, Action_DropThrow, Action_Place, Action_Shooting, Action_Drink, Action_Open, Action_Close, Action_Shout, Action_Pull, Action_Wear, Action_Light and Action_Unlock.

Rather than use item properties, the game just has separate objects that don't exist until an action is performed.

An example is:

Item ID	Item Name
02	"A match"
03	"A lighted match"

When the match is lit by the player; item 02 is destroyed and replaced with item 03.
