Used by the routines at Action_Examine, Action_Take, Action_DropThrow, Action_???, Action_Shooting, Action_Drink, Action_Open, Action_CloseShut, Action_Shout, Action_Pull, Action_Wear, Action_LightStrike 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
2	"A match"
3	"A lighted match"

When the match is lit by the player; item 2 is destroyed and replaced with item 3.
