Noisy Simon

I merged the Simon game with what I learned about making sounds, and managed to get a perfectly functional Simon game with sound. I changed the names of the sound channels so that I could refer to them by number instead of color, but other than that it's a pretty straight-forward adaptation.
One modification I made to the code was to add a 0.1 second delay with the sound in order to avoid the situation that the sound has not quite finished playing before the light goes off, thus creating a situation where you press a button and no sound comes out. I stumbled across this error while playing around with it, and since adding the delay this has not been a problem.
This is the end of what I consider to be things I kind of already knew how to do. The next step for me is to go into the graphical world of pygame.
