    EMeetingStore: added XFB detail extration/storing (heals build)
    
    * extract X-SUMMARY and X-LOCATION XFB details from a
      vfreebusy ical property (which is part of the ical
      component we get from the backends when querying
      free/busy information), either of which may be absent
    * the values we get will be validated for UTF-8 conformance
      (possibly being forced into) and length limited before
      being stored into the EMeetingAttendee alongside the
      other busy period details
