Modified sprite event mechanism to used classes derived from SpriteEvent

rather than codes to indicate different types of events. Also modified
name of sprite observer callback as spriteChanged() implies that the
sprite actually changed which it may not have, whereas handleEvent()
doesn't imply anything other than the sprite observer is being asked to
deal with a sprite event.
