[racket] sound + universe report: success.

The one I linked the first time

https://github.com/get-bonus/get-bonus/blob/master/exp/3s.rkt

and an example of its use

https://github.com/get-bonus/get-bonus/blob/master/games/tennis/tennis.rkt

Because the big-bang on-tick functions returns a list of sounds and
sounds are really functions of the world state, you can easily have on
going sounds by ensuring that it never returns #f (although you may
wish to have different background music per "level", which would be a
property of the world state) and transitory sounds by returning the
"bump" noise whenever the ball hits the ground. You just need to
return a sound function once and big bang will keep it in its sound
list until it returns #f. So basically on the first frame you return
the background sound and in future frames you return sounds
appropriate to what is going on.
