calendar: pull November's sanctoral calendar (pre-1955 pull, 11/12)

19 saints (14 real winners + 5 stubs), plus a propers-slug update for the
pre-existing All Saints entry. Three monastic-calendar-specific
reassignments this month, the most of any month so far (St. Emilian
displacing St. Martin I Pope, who moves to a different date; St. Odo
demoting St. Pontian; St. Silvester Abbot displacing St. Peter of
Alexandria), plus All Saints of the Benedictine Order, a monastic-only
addition at Duplex II. classis. New exclusion category: All Souls' Day
(Nov 2) is a fundamentally different liturgical genre -- the Office of
the Dead -- out of scope the same way the Requiem rite isn't modeled
anywhere else in this app.
