propers: add January's collect and antiphon text

Real collect text for the 9 January saints that have one, plus a real
antiphon for the 3 that have one of their own (as opposed to falling back
to a generic Common-of-Saints text) — read directly from the reference
engine's fully-rendered output, not reconstructed from the raw source
files' own shorthand endings ($Per Dominum, $Qui vivis, etc.).

+    Let us pray.
+    O God, Who, through the teaching of the Blessed Apostle Paul, hast caused the light of the Gospel to shine throughout the world, grant, we beseech thee, that we, having his wonderful conversion as on this day in remembrance, may show forth our thankfulness unto thee for the same, by following the holy example which he hath set.
+    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.
