New clock - Black and white

@PeerDavid - nice to see the Black and White clock all checked in and available on the main loader now. I love this clock - one of the nicest clocks done so far.

One small comment - I notice that when you click left or right there is an annoying delay, ie the UI does not feel responsive. This seems to be because the settings are being witten out again each time.

Could I suggest do the draw first, then the buzz, then write the settings. Maybe you could consider writing the settings using the on('kill') event instead. This would eliminate the apparent unresponsiveness.

E.on('kill', function() { ... });
