title: ID of an event (Fullcalendar)
body: <p>I need add an id to every single event from Fullcalendar, I found this <a href="http://arshaw.com/fullcalendar/docs/event_data/Event_Object/">http://arshaw.com/fullcalendar/docs/event_data/Event_Object/</a> but I don't know how, this id is<br>
  unique for every single event, because then I save the events in a Mysql database. Thanks</p>
