Add full Gospel pericopes to post-Epiphany through Palm Sunday Matins readings

Same gap as the Advent/Christmas sweep: Nocturn 3's patristic homily
appeared with no Gospel pericope before it. Authors the full text for
post-epiphany-1 through -6, septuagesima/sexagesima/quinquagesima,
lent-1 through -4, passion-sunday, and palm-sunday.

Palm Sunday needed a different source than the rest: its Missale
[Evangelium] tag is the Passion narrative (Matt 26-27) proclaimed at
Mass, not the entry-into-Jerusalem pericope (Matt 21:1-9) its own
Nocturn 3 homily is actually about — that shorter Gospel is instead
read at the Blessing of Palms, sourced from there.

Hoc autem totum factum est, ut adimplerétur, quod dictum est per Prophétam, dicéntem: Dícite fíliæ Sion: Ecce, Rex tuus venit tibi mansuétus, sedens super ásinam et pullum, fílium subjugális. Eúntes autem discípuli, fecérunt, sicut præcépit illis Jesus. Et adduxérunt ásinam et pullum: et imposuérunt super eos vestiménta sua, et eum désuper sedére fecérunt. Plúrima autem turba stravérunt vestiménta sua in via: álii autem cædébant ramos de arbóribus, et sternébant in via: turbæ autem, quæ præcedébant et quæ sequebántur, clamábant, dicéntes: Hosánna fílio David: benedíctus, qui venit in nómine Dómini.

+        At that time, when Jesus drew nigh to Jerusalem, and was come to Bethphage, unto Mount Olivet, then He sent two disciples, saying to them: Go into the village that is over against you, and immediately you shall find an ass tied, and a colt with her; loose them and bring them to Me; and if any man shall say anything to you, say that the Lord has need of them, and forthwith he will let them go. Now all this was done that it might be fulfilled which was spoken by the prophet, saying: Tell the daughter of Sion: Behold your King comes to you meek, and sitting upon an ass, and a colt the foal of her that is used to the yoke. And the disciples going did as Jesus commanded them. And they brought the ass and the colt, and laid their garments upon them, and made Him sit thereon. And a very great multitude spread their garments in the way, and others cut boughs from the trees, and strewed them in the way, and the multitudes that went before and that followed cried, saying: Hosanna to the Son of David; blessed is He that comes in the Name of the Lord.
