Making Rock Piano a little less rock, but more performant

[andreasbovens]

I've played around with Patrick's beatbox demo and replaced the beats with piano notes, and this performs very well without reverb. Check http://people.opera.com/andreasb/exp/rock/beatpiano.html on tablet.

So, my suggestion would be to do the following:

• remove the JS logic for looping etc, and just stick to a simple "on press, I should hear a sound for a while" idea like in Patrick's demo. This can be achieved with very simple markup and that's good enough for MWC.
• fade out and possible shorten the music notes. You could also re-record them from Garageband or so. Also play with quality levels so as to get small file sizes.
  (- store the notes offline with appcache.)
