title: Cannot select years BC
body: <p>I'm working on a project that need to handle dates BC (eg 100BC, or 2000BC) as well as 2014AC etc..</p>
  
  <p>In the <a href="http://api.jqueryui.com/datepicker">API</a> documentation of Datepicker, it is stated that <code>minDate</code> and <code>maxDate</code> can be set using javascript <code>Date</code> object (with has min and max of aprox <a href="http://msdn.microsoft.com/en-us/library/ie/cd9w2te4%28v=vs.94%29.aspx">285,616</a> years on either side of 1970).</p>
  
  <p>It seems to be impossible to set years in BC or even before 1/1/99.</p>
  
  <pre><code>$("#date").datepicker({
      dateFormat: 'dd-mm-yy',
      showButtonPanel: true,
      changeMonth: true,
      changeYear: true,
      yearRange: '0:2010',
      inline: true });
  </code></pre>
  
  <p>How can I surpass this limit?</p>
