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.).
