title: Change the week start day on DTPicker
body: <p>Is it possible to change the Day of the Week that the DTPicker control uses for the first day of the week 'on the fly'?</p>
  
  <p>I know that it uses the system first day of the week (as defined in control panel) for this setting but can it be changed to use another day without changing the control panel setting? </p>
