Fixed a bug where seconds were not cleared after interaction until next minute tick. Changed default theme to light, after getting a real device, the contrast ratios worked better with black text on a white background. The colours are still fully customisable though.
Added option to display seconds after wrist flick. I think it's stable, it runs great in the emulator, but I don't have a Pebble Time 2 yet (they haven't started shipping them yet), so I haven't been able to test it on real hardware.
