Add October Matins readings for SanctiM-track saints

9 of October's 13 SanctiM-track saints authored. Found a new wrinkle:
St. Justina and St. Gall are genuinely Monastic-only (no Tridentine
file at all) but their own SanctiM files turn out to be Common-only
with no proper Lectio content -- being Monastic-only doesn't guarantee
real text to transcribe.

+        Lucas médicus Antiochénsis ut ejus scripta índicant, Græci sermónis non ignárus, fuit
+        sectátor Apóstoli Pauli, et omnis peregrinatiónis ejus comes. Scripsit Evangélium, de
+        quo idem Paulus: Mísimus, inquit, cum illo fratrem, cujus laus est in Evangélio per
+        omnes ecclésias. Et ad Colossénses: Salútat vos Lucas, médicus caríssimus. Et ad
+        Timótheum: Lucas est mecum solus. Aliud quoque édidit volúmen egrégium, quod título,
+        Acta Apostolórum, prænotátur: cujus história usque ad biénnium Romæ commorántis Pauli
+        pervénit, id est, usque ad quartum Nerónis annum. Ex quo intellégimus in eádem urbe
+        librum esse compósitum.
+
+
+        Igitur períodos Pauli et Theclæ, et totam baptizáti Leónis fábulam, inter apócryphas
+        scriptúras computámus. Quale enim est, ut indivíduus comes Apóstoli, inter céteras
+        ejus res, hoc solum ignoráverit? Sed et Tertulliánus, vicínus eórum témporum, refert
+        presbýterum quemdam in Asia, amatórem Apóstoli Pauli, convíctum a Joánne quod auctor
+        esset libri, et conféssum se hoc Pauli amóre fecísse, et ob id loco excidísse. Quidam
+        suspicántur, quotiescúmque in epístolis suis Paulus dicit, Juxta Evangélium meum, de
+        Lucæ significáre volúmine.
+
+
+        Lucam autem, non solum ab Apóstolo Paulo didicísse Evangélium, qui cum Dómino in
+        carne non fúerat, sed et a céteris Apóstolis; quod ipse quoque in princípio sui
+        volúminis declárat, dicens: Sicut tradidérunt nobis, qui a princípio ipsi vidérunt et
+        minístri fuérunt sermónis. Igitur Evangélium, sicut audíerat, scripsit; Acta vero
+        Apostolórum, sicut víderat ipse, compósuit. Vixit octogínta et quátuor annos, uxórem
+        non habens. Sepultus est Constantinópoli, ad quam urbem, vigésimo Constantíni anno,
+        ossa ejus cum relíquiis Andréæ Apóstoli transláta sunt de Achája.

+        Luke was a physician of Antioch, who, as appeareth from his writings, knew the Greek
+        language. He was a follower of the Apostle Paul, and his fellow traveller in all his
+        wanderings. He wrote a Gospel, whereof the same Paul saith: We have sent with him the
+        brother, whose praise is in the Gospel throughout all the Churches. Of him, he writeth
+        unto the Colossians: Luke, the beloved physician, greeteth you. And again, unto
+        Timothy: Only Luke is with me. He also published another excellent book entitled The
+        Acts of the Apostles, wherein the history is brought down to Paul's two years sojourn
+        at Rome, that is to say, until the fourth year of Nero, from which we gather that it
+        was at Rome that the said book was composed.
+
+
+        The silence of Luke is one of the reasons why we reckon among Apocryphal books The
+        Acts of Paul and Thecla, and the whole story about the baptism of Leo. For why should
+        the fellow traveller of the Apostle, who knew other things, be ignorant only of this?
+        At the same time there is against these documents the statement of Tertullian, almost a
+        contemporary writer, that the Apostle John convicted a certain Priest in Asia, who was
+        a great admirer of the Apostle Paul, of having written them, and that the said Priest
+        owned that he had been induced to compose them through his admiration for Paul, and
+        that he was deposed in consequence. There are some persons who suspect that when Paul
+        in his Epistles useth the phrase: According to my Gospel, he meaneth the Gospel written
+        by Luke.
+
+
+        However, Luke learned his Gospel not from the Apostle Paul only, who had not companied
+        with the Lord in the flesh, but also from other Apostles, as himself declareth at the
+        beginning of his work, where he saith: They delivered them unto us, which from the
+        beginning were eyewitnesses and ministers of the word. According to what he had heard,
+        therefore, did he write his Gospel. As to the Acts of the Apostles, he composed them
+        from his own personal knowledge. He was never married. He lived eighty-four years. He
+        is buried at Constantinople, whither his bones were brought from Achaia in the
+        twentieth year of Constantine, together with the relics of the Apostle Andrew.
