propers: add December's collect and antiphon text

10 collects, 5 antiphons -- including backfilling the pre-existing
Immaculate Conception entry. St. Damasus's collect is Latin-only (no
English translation exists in the reference source at all); a few
others (All Saints, Bibiana, Immaculate Conception) needed their English
read directly from the raw source file after the live query's English
side either omitted the Oratio translation or rendered the wrong Marian
feast's text -- caught by cross-checking, not assumed.

+    Deus, ómnium largítor bonórum, qui in fámula tua Bibiána cum virginitátis flore martýrii palmam conjunxísti: mentes nostras ejus intercessióne tibi caritáte conjúnge; ut, amótis perículis, prǽmia consequámur ætérna.

+    ℟. Amen.

+    Let us pray.
+    O God, the Giver of all good gifts, Who unto the lily of pure maidenhood in the hand of thy servant Bibiana, didst join the palm of a glorious martyrdom, grant us, we beseech thee, at her pleading, that our hearts and minds being joined to thee by thy love, we may escape all dangers which do presently beset us, and finally attain unto thine everlasting joy.
+    Who livest and reignest with God the Father, in the unity of the Holy Spirit, God, world without end.
+    ℟. Amen.
