title: add event to fullcalendar by dropping from external source
body: <p>I would like to add an event to the fullcalendar jquery plugin from an external source. I need the event title; start and end dates.  I read that the <code>drop</code> callback function is called when you drop an external source on the calendar.  This reports the start date in the alert.  The <code>eventReceive</code> option shows the title of the event.  This alert is displayed after the <code>drop</code> callback.  This is the code:</p>
  
  <pre><code>$('#edit_calendar').fullCalendar({
  ...
   droppable: true,
   drop: function(date) {
          alert("Dropped on " + date );
   },
  eventReceive: function (event) {
           alert('event, ' + event.title + ', was added, (need date here)');
   },
  </code></pre>
  
  <p>How do I get the start date value from the <code>drop</code> callback to the <code>eventRecieve</code> function?</p>
