propers: octave readings for the Immaculate Conception

Corrects the earlier "no Matins content exists" conclusion (previous
commit): that was true of the live prayMatutinum query specifically,
scoped to "Monastic Tridentinum 1617" -- which naturally selects nothing,
since the dogma wasn't defined until 1854. The reference project's raw
"bmv"-suffixed variant files (12-09bmv.txt through 12-14bmv.txt) do carry
real content: excerpts from Pope Pius IX's dogmatic bull "Ineffabilis
Deus" joined with a different Marian homily each day (Sophronius,
Bernard, Tarasius). Included per explicit user direction -- this
project's octave content is deliberately more generous than the strict
1617 monastic rubric alone would select.

Days 4 (Dec 11) and 6 (Dec 13) genuinely have no reading of their own in
the source (confirmed directly in the raw files, not assumed) -- both
already belong to another saint's own feast (Damasus, Lucy) anyway. Day
8 has no "bmv" variant file at all.

Also fixes two more source typos found while transcribing ("Himselfcan"
-> "Himself can", "Onlybegotten" -> "Only-begotten").

+    Quoniam quæ ad cultum pertinent, intimo plane vinculo cum ejusdem objecto conserta sunt, neque rata et fixa manere possunt, si illud anceps sit et in ambiguo versetur, idcirco decessores nostri Romani Pontifices omni cura Conceptionis cultum amplificantes illius etiam objectum ac doctrinam declarare, et inculcare impensissime studuerunt. Etenim clare aperteque docuere, festum agi de Virginis Conceptione, atque uti falsam et ab Ecclesiæ mente alienissimam proscripserunt illorum opinionem qui non Conceptionem ipsam, sed sanctificationem ab Ecclesia coli arbitrarentur et affirmarent.
+
+    Neque mitius cum iis agendum esse existimarunt, qui ad labefactandam de Immaculata Virginis Conceptione doctrinam excogitato inter primum atque alterum Conceptionis instans et momentum discrimine, asserebant, celebrari quidem Conceptionem sed non pro primo instanti atque momento. Ipsi namque prædecessores nostri suarum partium esse duxerunt, et beatissimæ Virginis Conceptionis festum, et Conceptionem pro primo instanti tamquam verum cultus objectum omni studio tueri ac propugnare.
+
+    Atque illud in primis solemne quoque fuit iisdem decessoribus nostris, doctrinam de Immaculata Dei Matris Conceptione sartam tectamque omni cura, studio et contentione tueri. Neque his contenti, ut ipsa de Immaculato Virginis Conceptu doctrina inviolata persisteret, opinionem huic doctrinæ adversam, sive publice, sive privatim, defendi posse severissime prohibuere, eamque multiplici veluti vulnere confectam esse voluerunt.
+
+    Quibus te laudibus cumulabimus, Maria? O puella immaculata; o virgo impolluta; mulierum ornamentum filiarum nitor! O mater Virgo sancta, tu benedicta inter mulieres; tu celebrata propter innocentiam; tu obsignata virginitate. Tu Adami maledicti expiatio; tu debiti Hevæ solutio. Tu Abelis purissima oblatio; primogenitorum delectus; immaculatum sacrificium. Tu Enos in Deum spes non pudore suffusa; tu Enoch inita gratia, et in securam vitam migratio. Tu Noë arca, et secundæ regenerationis apud Deum conciliatio. Tu regni et sacerdotii Melchisedech perillustris splendor; tu Abrahami firma fiducia et promissionis futuræ posteritatis obsequens fides.
+
+    Tu es prophetarum speculum, et rerum ab illis prænuntiatarum exitus. Te enixe Ezechiel vaticinans appellavit portam clausam, per quam nemo hominum umquam transibit nisi Dominus Deus solus, et portam clausam conservabit. Te Isaias ille in primis grandiloquus prænuntiat virgam Jesse, ex qua flos Christus orietur. Te Jeremias præmonstravit inquiens: Ecce dies venient, dicit Dominus, et feriam domui Israël et domui Judæ fœdus novum. Te étiam Daniel vir desideriorum proclamavit montem ingentem, e quo Christus lapis angularis abscindetur. Te honoro agnam immaculatam, te prædico gratia plenam, te cano Dei habitationem puram et immaculatam.
+
+    Nos autem populus Dei, gens sancta, congregatio acceptabilis, filii columbæ, soboles gratiæ in hac Virginis celebritate puris animis, impollutis labiis, multisonis linguis hymnos suavidicos extollamus. Ave delicium Patris, per quam ad ultimos terræ fines Dei cognitio manavit. Ave Filii domicilium, de qua ille carne indutus prodivit. Ave sancti Spiritus habitaculum ineffabile. Ave sanctior Cherubim; ave gloriosior Seraphim; ave cælo altior; ave sole splendidior; ave luna micantior. Ave causa salutis omnium mortalium; ave regina pacis conciliatrix; ave matrum splendor immaculatus. Ave gratia plena, Dominus tecum, qui ante te, et ex te, et nobiscum. Ipsi laus cum Patre et sanctissimo et vivifico Spiritu, nunc et semper, et in infinita sæcula sæculorum. Amen.

+    The language used in public worship is the necessary offspring of the teaching which it expresseth, and the former can have no safety unless the latter be settled. Wherefore Our Predecessors the Roman Pontiffs, while encouraging the pious love of the faithful for the Conception of the Blessed Virgin, have taken care ceaselessly to inculcate the sinlessness of the same. They have always particularly insisted that the Feast should be observed not in honour of Mary's sanctification, a false opinion, most foreign to the mind of the Church, but in honour of her Conception itself.
+
+    The same Our Predecessors have likewise resisted the dreams of those who have imagined that in the sinless Conception there were Two Instants, and that the Church celebrateth the Second and not the First. Indeed, Our said Predecessors have considered the sinlessness of the First Instant to be as much a truth for their assertion, protection, and promulgation, as the sinlessness of the Conception at all.
+
+    It hath always been one of the most weighty cares of Our said Predecessors the Roman Pontiffs to protect the doctrine of the sinlessness of Mary's Conception from any sort of attack or corruption. Our said Predecessors did not stop even here, but in order to preserve the doctrine of the Virgin's sinless Conception from injury they strictly forbade that the opposite opinion should be maintained either in public or in private, to the end that it might at length die out under disapprobation.
+
+    O Mary, where shall I find words to praise thee? Maiden undefiled, virgin unstained, exaltation of women, glory of daughters! Holy Maiden Mother, blessed art thou among women, thy glory is in thy guilelessness, and thy name is a name of purity. In thee the curse of Adam is done away, and the debt of Eve paid. Thou art the clean offering of Abel, a pure sacrifice. Thou art the hope of Enoch, that firm hope that he had in God. Thou art the Holy Ark of Noah, and the bond of reconciliation with God in a new regeneration. Thou art the exceeding glory of the kingdom and Priesthood of Melchisedech. Thou art the unshaken trust of Abraham, and his faith in the promise of children that were to be.
+
+    Thou art the vision of the Prophets and the fulfilment of those things which they foretold. Thou art the gate whereof Ezekiel spake, when he prophesied, and said, This gate shall be shut, it shall not be opened, and no man shall enter in by it; because the Lord, the God of Israel, hath entered in by it. Thou art the Rod of Jesse, whereof Isaiah spake, even that Rod whose Flower is Christ. Thou art the Covenant foretold by Jeremiah, thereby signifying the coming of thy Son. Thou art the great mountain spoken of by Daniel, the man greatly beloved, wherefrom is cut without man's hands the corner-stone, that is, Christ. I honour thee as the unpolluted fountain, I proclaim that thou art full of grace, I praise thee as the clean and undefiled tabernacle of God.
+
+    And now we, the people of God, a holy generation, an acceptable congregation, the nestlings of the dove of peace, children of grace, do with purified minds and unpolluted lips, praise God in the tongues of all nations in this joyful solemnity of the Virgin. Hail, thou Paradise of God the Father, whence the knowledge of Him floweth in broad rivers to the ends of the earth! Hail, Dwelling-place of God the Son, whence He came forth clothed in flesh! Hail, mysterious Tabernacle of God the Holy Ghost! Hail, thou that art holier than the Cherubim! Hail, thou that art more glorious than the Seraphim! Hail, thou that art nobler than the heavens! Hail, thou that art brighter than the sun! Hail, thou that art fairer than the moon! Hail, source of health to dying creatures! Hail, O Queen, ambassadress of peace! Hail, stainless crown of motherhood! Hail, thou that art full of grace, the Lord is with thee, even the Lord that is before thee, and from thee, and that is with us. To Him, with the Father, and the most holy and Life-giving Spirit, be ascribed all praise, now and ever, world without end. Amen.
