Add September Matins readings for SanctiM-track saints

All 9 of September's SanctiM-track saints authored -- the first full
month in this pass with nothing left unsourced. Includes the
Dedication of St. Michael the Archangel, whose SanctiM file borrows
structure from his separate May 8 Apparition file but still resolves
its actual readings back to this day's own Tridentine content.

+# Matins Nocturn 2 reading for Ss. Cosmas and Damian, Martyrs (Sep 27)
+# — SanctiM/09-27.txt inherits the whole day (`@Sancti/09-27`) with no
+# Nocturn 2/3 override, so this feast's own proper content is sourced
+# from the Tridentine track exactly as for a pre-1955 saint (see
+# memory vu-matins-pre1955-saints, vu-matins-sanctim-saints).
+# web/www/horas/Latin/Sancti/09-27.txt, English/Sancti/09-27.txt.
+# Lectio4-5 combined into one reading, one continuous vita — Lectio6
+# falls back to Common of Several Martyrs, not proper text, so not
+# authored here. No responsory given in the source for Lectio4-5.

+        Cosmas et Damiánus, fratres Arabes, in Ægéa urbe nati, nóbiles médici, imperatóribus
+        Diocletiáno et Maximiáno, non magis medicínæ sciéntia quam Christi virtúte, morbis
+        étiam insanabílibus medebántur. Quorum religiónem cum Lysias præféctus cognovísset,
+        addúci eos ad se jubet, ac de vivéndi institúto et de fídei professióne interrogátos,
+        cum se et Christiános esse, et christiánam fidem esse ad salútem necessáriam, líbere
+        prædicárent, deos venerári ímperat; et, si id recúsent, minátur cruciátus et necem
+        acerbíssimam.
+
+
+        Verum, ut se frustra hæc illis propónere intélligit: Colligáte, inquit, manus et
+        pedes istórum, eósque exquisítis torquéte supplíciis. Quibus jussa exsequéntibus,
+        nihilóminus Cosmas et Damiánus in senténtia persistébant. Quare, ut erant vincti, in
+        profúndum mare jaciúntur. Unde cum salvi ac solúti essent egréssi, mágicis ártibus
+        præféctus factum assígnans, in cárcerem tradit, ac postrídie edúctos in ardéntem
+        rogum ínjici jubet; ubi, cum ab ipsis flamma refúgeret, várie et crudéliter tortos
+        secúri pércuti vóluit. Itaque, in Jesu Christi confessióne, martýrii palmam
+        accepérunt.

+        Cosmas and Damian, who were eminent physicians in the time of the Emperors Diocletian
+        and Maximian, were brothers, and Arabs by race, but born in the city of Aegae. Not more
+        by their knowledge of medicine than by the power of Christ they healed diseases which
+        had been hopeless for others. When the Praefect Lysias learnt to what faith they
+        belonged, he commanded them to be brought before him, and questioned them as to their
+        way of life, and the confession of their religion; and then, forasmuch as they freely
+        owned themselves Christians and the Christian faith needful to salvation, he commanded
+        them to worship the gods, under threats of torments and a most cruel death.
+
+
+        He bond their hands and feet together, and put them to the sharpest of the question.
+        And he was obeyed, but nevertheless Cosmas and Damian abode still of the same mind.
+        Therefore they were cast into the depth of the sea, bound as they were, but they came
+        forth again, whole and unbound. The Praefect, therefore, who would have it that it came
+        to pass so by force of art magic, cast them into prison. On the morrow he haled them
+        forth again, and bade cast them upon a great fire, but the flame turned away from them.
+        He was pleased then to have them tormented in diverse and cruel sorts, and lastly,
+        smitten with the axe. Thus did they bear witness for Christ Jesus even until they
+        grasped the palm of their testimony.
