title: fullCalendar: Extra week displayed after September
body: <p>I see that using v2.1.1 there is an extra week displayed after September - so the first 10 days of October are displayed there.</p>
  
  <p>Examples: </p>
  
  <ul>
  <li>can be seen right now on the home page of <a href="http://arshaw.com/fullcalendar/" rel="noreferrer">http://arshaw.com/fullcalendar/</a> </li>
  <li>And also at: <a href="http://jsfiddle.net/dLsnqomc/" rel="noreferrer">http://jsfiddle.net/dLsnqomc/</a></li>
  <li>And screen cap below... </li>
  </ul>
  
  <p>Code:</p>
  
  <pre><code>&lt;div id="calendar"&gt;&lt;/div&gt;
  
  $('#calendar').fullCalendar();
  </code></pre>
  
  <p>Any idea how to remove the superfluous last week (October 5-11)?</p>
  
  <p>Thanks
