Add rank data to named temporal feast records

TemporalFeastRecord had no rank field at all, so Christmas/Pentecost/
Christ the King/Marian Saturday had nothing for the day label to show.
Christmas, Pentecost, and Christ the King are Duplex I Class (the
latter's own file comment already said so); Marian Saturday is a
Simplex-strength votive commemoration.
