Add momentum scrolling on iOS

[bertrandbuild]

When accessing to the dashboard on iOS the the scroll is "hard".

Should be solved with :

  overflow-y: scroll; /* has to be scroll, not auto */
  -webkit-overflow-scrolling: touch;

Thanks for reporting @Palisanka.
We plan to do some work on the Home screen soon, so I'm pinging @m4dz ;-)
