E18C: Handle Sparkle
Handler for the object types 72 and 73 the sparkle that shows where a bubble has burst (see Handle_Bubble). The counter in byte 08 goes down on each call and the sprite id alternates between 72 and 73 with it. The sparkle is removed (and erased) when the counter reaches zero, and at once if Sabreman is not in the room.
