title: jquery DatePicker - numeric month dropdown
body: <p>I have an HTML input element for my datepicker... pretty normal</p>
  
  <pre><code>&lt;input type="text" id="from_date"&gt;
  </code></pre>
  
  <p>And a pretty normal setup for allowing the Month / Year changes</p>
  
  <pre><code>$('#from_date').datepicker({
      dateFormat: "mm/yy",
      changeMonth: true,
      changeYear: true
  });
  </code></pre>
  
  <p>But the Month dropdown shows names like "Jan" instead of "1" or "01"</p>
  
  <p>How can I change the dropdown values to be the numerical representation?</p>
