Date and time pickers do not show properly on phone

1. Copied the default NumberPicker layout to sw-600dip
   i.e. in the layouts for tablets and changed the
   layout to fit on the screen. No mini calendar on
   phones - you need an microsope to see it.

2. Fixed a two pixel off erroro in NumberPicker noticable
   when the scroll wheel fades away.
