48864: Handle Extra Life
The handler for an extra life (object 12). When the player touches it the object turns into a sparkle, it is removed from the table of special objects, the egg tops are allowed to move again and a life is added and printed in the panel. An extra life which has not been touched is moved with gravity and makes a sound when it moves.
