Add July Matins readings for SanctiM-track saints

13 of July's 18 SanctiM-track saints authored (5 left unsourced,
Common-only). Discovered the Monastic calendar keeps a full Octave of
St. Benedict (Jul 11-18), which explains several dates' SanctiM files
not matching their expected saint. Also hit a translation-misalignment
bug on St. Bonaventure's English source (paragraph boundaries don't
line up with the Latin), worked around with an original translation.

+# Matins Nocturn 2 reading for St. Alexius, Confessor (Jul 17). No
+# genuine SanctiM match: the SanctiM files for this date,
+# `SanctiM/07-17Moct.txt`/`07-17M.txt`, belong respectively to the
+# Octave of St. Benedict (Jul 11-18) and to a different saint (St. Leo
+# IV) — a missed pre-1955-pool candidate rather than a genuine SanctiM
+# case (see memory vu-matins-pre1955-saints, vu-matins-sanctim-saints).

+# Single lesson (Lectio4 — Lectio5-6 fall back to Common of a
+# Confessor, not proper text, so not authored here). No responsory

+        Aléxius, Romanórum nobilíssimus, propter exímium Jesu Christi amórem prima nocte
+        nuptiárum peculiari Dei mónitu relínquens intactam sponsam, illustrium orbis terræ
+        ecclesiárum peregrinatiónem suscépit. Quibus in itinéribus cum ignotus septémdecim
+        annos fuísset, aliquándo apud Edessam, Syriæ urbem, per imáginem sanctíssimæ Maríæ
+        Vírginis, ejus nómine divulgato, inde navi discessit. Ad portum Romanum appulsus, a
+        patre suo tamquam alienus pauper hospítio accipitur; apud quem, ómnibus incógnitus,
+        cum decem et septem annos vixísset, relícto scripto sui nóminis, sánguinis, ac totius
+        vitæ cursus, migrávit in cælum, Innocentio primo summo Pontifice.

+        Alexis was a member of one of the noblest Roman families. Through his exceeding great
+        love for Jesus Christ, he received a particular command from God to leave his bride
+        untouched upon his wedding night, and to undertake a pilgrimage to the most famous
+        Churches of the world. For seventeen years he remained occupied in these journeys and
+        utterly unknown. At the end of that time, his name was spoken from an image of the most
+        holy Virgin Mary in the city of Edessa, in Syria, and when he found himself recognised he
+        took ship from thence. He landed at Porto near Rome, and fared to the house of his own
+        father, who gave him shelter as a strange beggar. He lived there unrecognised by any for
+        seventeen years more, and then passed away to heaven, in the time of Pope Innocent I. He
+        left behind him a writing giving his name, family, and the story of his life.
