propers: add October's collect text

Companions) that changes their governing behavior -- same class of
collision as previous months.

+    Let us pray.
+    O God, Who didst use thine holy Apostles Simon and Jude to make known unto us thy Name, grant unto us so to profit by their doctrine as to do honour to their everlasting glory, and so to honour that glory as to gain profit to ourselves.
+    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.
