title: Impossible to select all_day_slots with fullcalendar
body: <p>I am using <a href="http://fullcalendar.io/">fullcalendar</a> to create a calendar where my user can indicate his disponibilities. I have set up the calendar so there are allDaySlots available. They appear correctly on the calendar, but I can't select them. Is there anything special to specify in the select callback?</p>
  
  <p>Is it also possible to set up fullcalendar so that when the user selects the allDaySlot, the whole row concerning that day appears as selected?</p>
