Takes one of the lives of the player, or ends the game if there are none left. The player is set to the vanishing sprite 67 (see HandlerPlayerVanishing), with the number of rows to erase (at offset 06) set to the height of the sprite and the sprite ID that it came from (at offset 07). If the entity is a character then the position that was saved by StoreEntity is used first.
