Add June sanctoral content: 6 saints

Continues the full-year sanctoral import: St. Angela Merici, St. Francis
Caracciolo, St. Boniface of Mainz (Bishop and Martyr, Apostle of Germany --
distinct from the earlier, unrelated St. Boniface Martyr already on May 14),
St. Norbert, St. Margaret of Scotland, and St. Aloysius Gonzaga.

Two of the new fixed dates (June 1, June 4) fall on dates used by two
day-label tests pinned to specific Trinity Sunday years; moved those to
years/dates free of the new entries, with explanatory comments.

+        Norbértus, nobilíssimis paréntibus natus, adoléscens liberálibus disciplínis
+        erudítus, in ipsa póstea imperatóris aula, spretis mundi illécebris,
+        ecclesiásticæ milítiæ adscríbi vóluit. Sacris initiátus, rejéctis móllibus ac
+        spléndidis véstibus, pellícea melóte indútus, prædicatióni verbi Dei se totum
+        dedit. Abdicátis ecclesiásticis provéntibus satis amplis, et património in
+        páuperes erogáto, semel in die sub vésperam solo cibo quadragesimáli utens,
+        nudísque pédibus et lácera veste sub brumáli rigóre incédens, miræ
+        austeritátis vitam est aggréssus. Potens ígitur ópere et sermóne, innúmeros
+        hæréticos ad fidem, peccatóres ad pœniténtiam, dissidéntes ad pacem et
+        concórdiam revocávit.
+
+
+        Cum Laudúni esset, ab epíscopo rogátus ne a sua diœcési discéderet, desértum
+        in ea locum, qui Præmonstrátus dicebátur, sibi delégit; ibíque, trédecim
+        sóciis aggregátis, Præmonstraténsem órdinem instítuit, divínitus accépta per
+        visum régula a sancto Augustíno. Cum vero ejus fama sanctitátis in dies magis
+        augerétur, ac plúrimi ad eum quotídie discípuli convenírent, idem ordo ab
+        Honório secúndo aliísque summis Pontifícibus confirmátus, ac plúribus ab eo
+        monastériis ædificátis, mirífice propagátus est.

+        Antvérpiam accersítus, in ea urbe Tanchelíni nefáriam hæresim profligávit.
+        Prophético spíritu et miráculis cláruit. Archiepíscopus tandem (licet
+        relúctans) Magdeburgénsis creátus, ecclesiásticam disciplínam, præsértim
+        cælibátum, constánter propugnávit. Rhemis in concílio Innocéntium secúndum
+        egrégie adjúvit, et Romam cum áliis epíscopis proféctus, schisma Petri Leónis
+        compréssit. Postrémo vir Dei, méritis et Spíritu Sancto plenus, Magdebúrgi
+        obdormívit in Dómino, anno salútis millésimo centésimo trigésimo quarto, die
+        sexta Júnii.

+        Norbert, born in the year 1080 of parents of the highest rank, thoroughly
+        educated in his youth in worldly knowledge, and a member of the Imperial
+        court, turned his back upon the glory of the world, and chose rather to enlist
+        himself as a soldier of the Church. Being ordained Priest, he laid aside all
+        soft and showy raiment, clad himself in a coat of skins, and made the
+        preaching of the Word of God the one object of his life. He had the right to
+        rich revenues of the Church but these he renounced, and to an ample fortune
+        from his father; but this he gave to the poor. He ate only once a day, and that
+        in the evening, and then his meal was of the fare of Lent. His life was one of
+        singular hardness, and he was used even in the depth of winter to go out with
+        bare feet and ragged garments. Hence came that mighty power of his words and
+        deeds, whereby he was enabled to turn countless heretics to the true faith,
+        sinners to repentance, and enemies to peace and brotherly love.
+
+
+        Being one while at Laon, the Bishop besought him not to leave his diocese, and
+        he therefore made choice of a wilderness at the place called Prémontré,
+        whither he withdrew himself with thirteen disciples, and thus founded the
+        Order of the Praemonstratensian Canons, whereof he, by the will of God,
+        received the Rule, in a vision, from St. Augustine. When, however, the fame of
+        his holy life became every day more and more noised abroad, and great numbers
+        sought to become his disciples, and the Order had been approved by Honorius
+        II, and other Popes, many more monasteries were built by him, and the
+        Institute wonderfully extended.
+
+
+        Being called to Antwerpen, he there gave the death-blow to the shameful heresy
+        of Tanchelm. He was remarkable for the spirit of prophecy and for the gift of
+        miracles. He was created (albeit he would rather not have had it so)
+        Archbishop of Magdeburg, and as such he was a strong upholder of the discipline
+        of the Church, especially contending against the marriage of the clergy. At a
+        Council held at Reims he was a great help to Innocent II, and went with some
+        Other Bishops to Rome, where they stamped out the schism of Peter Leoni. It was
+        at last at Magdeburg that this man of God, full of good works and of the Holy
+        Ghost, fell asleep in the Lord, on the 6th day of June, in the year of
+        salvation 1134.
