function _date_ical_convert_rrule_for_icalcreator in Date iCal 7.3

Convert an rrule array to the iCalcreator format.

iCalcreator expects the BYDAY element to be an array like this: (array) ( [([plus] ordwk / minus ordwk)], "DAY" => weekday )

But the way that the Date API gives it to us is like this: (array) ( [([plus] ordwk / minus ordwk)]weekday )

      // iCalcreator doesn't expect the 'DATA' key that the Date API gives us.
      continue;
    }
    if (strtoupper($key) == 'UNTIL') {

      // iCalcreator expects the 'timestamp' to be array key for UNTIL.

      $new_byday = array();

        $ordwk = substr($day, 0, -2);
