title: Render event on top fullcalendar
body: <p>We are using the jquery plugin fullCalendar for a project at work. However, we want to display certain events with certain properties on top in each day column. The problem is that I don't want to change the source code of Fullcalendar.js if I don't have to and it even seems that it's using the minified .js for rendering events.</p>
  
  <p>I know that it exists a trigger that triggers an custom event <code>eventRender: function (event, element)</code> but I'm out on ideas to render the event at top. For this example we might say that event got an <code>important</code> attribute.</p>
  
  <p>So I guess this psuedo-code will make my example more clear:</p>
  
  <pre><code>eventRender: function (event, element) {
      if(event.important) {
          //render at top
      }
  }
  </code></pre>
