Add accelerometer#181

As the Soundbrenner core already has Smartwatch features, why not add an accelerometer so that it can track steps and other motion/health data? As it is now, it is a great looking watch to wear all day, but I have to replace it with a Fitbit or Garmin to workout. Why not have it all in one great product. Also considering the cost, you should allow trade ins when redesigns of the hardware are available and start a donation program of older models to music programs in underprivileged schools.

Thanks for the feedback, I merged it with a similar suggestion :)
