Add June sanctoral content: 6 saints

Continues the full-year sanctoral import: St. Angela Merici, St. Francis
Caracciolo, St. Boniface of Mainz (Bishop and Martyr, Apostle of Germany --
distinct from the earlier, unrelated St. Boniface Martyr already on May 14),
St. Norbert, St. Margaret of Scotland, and St. Aloysius Gonzaga.

Two of the new fixed dates (June 1, June 4) fall on dates used by two
day-label tests pinned to specific Trinity Sunday years; moved those to
years/dates free of the new entries, with explanatory comments.

+    Let us pray.
+    O God, Who didst raise up thy blessed servant Francis to found a new Order in thy
+    Church, and didst ennoble him through earnestness in prayer and love of penance,
+    grant unto us after his example so to pray without ceasing and to bring our bodies
+    into subjection, that, in the end, we, like him, may worthily attain unto thy
+    heavenly glory.
+    Through Jesus Christ, thy Son our Lord, Who liveth and reigneth with thee, in the
+    unity of the Holy Ghost, God, world without end.
+    ℟. Amen.
