title: how to disable dates before today in jQuery datepicker
body: <p>How do I disable dates before today in jQuery datepicker <strong>WITHOUT using <code>minDate: 0</code></strong>?</p>
  
  <p>I would like to enable navigation of the calendar as per usual before today while making sure that user do NOT pick dates before today.</p>
  
  <p>(i.e. say today's date is 11Aug11 and I would like all the dates before this disabled but still enabling user to go to previous months, years, etc.)</p>
