title: How to make only eventSources droppable into FullCalendar?
body: <p>i use FullCalendar and i call my Event with eventSources and ajax like this :</p>
  
  <pre><code>eventSources: 
          [
              {
                  url: 'ajax.php',
                  type: 'POST',
                  data: {
                     obj: 'Event'
                  },
                  error: function() {
                      alert('there was an error while fetching events!');
                  }
  
              },          
          ],
  </code></pre>
  
  <p>the Return JSON Code look like this : </p>
  
  <pre><code>[{"id":"1","name":"Event One","town":"London","start":"2011-05-10","url":"","title":"Event One","className":"Event_class","description":"Hier some description","color":"#D42993","draggable":"false"},{another Events}]
  </code></pre>
  
  <p>So far it's all good, then i tried to make just those event Droppable(not the Calendar), so that i can drag an external object into it(for example a "Manager").</p>
  
  <p>I change the eventSources in this way but it dont work :</p>
  
  <pre><code>eventSources: 
          [
              {
                  url: 'ajax.php',
                  type: 'POST',
                  data: {
                     obj: 'Event'
                  },
                  error: function() {
                      alert('there was an error while fetching events!');
                  },
                  textColor: 'black',
                                      disableDragging: true,
                  cache: true,
                                      dropAccept: '.Personal',
                  droppable : true,
                                      eventDrop: function(e, ui){ alert("drop")}
              },          
          ],
  </code></pre>
