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.

Cum autem dormírent hómines, venit inimícus ejus, et superseminávit zizánia in médio trítici, et ábiit. Cum autem crevísset herba et fructum fecísset, tunc apparuérunt et zizánia. Accedéntes autem servi patrisfamílias, dixérunt ei: Dómine, nonne bonum semen seminásti in agro tuo? Unde ergo habet zizánia? Et ait illis: Inimícus homo hoc fecit. Servi autem dixérunt ei: Vis, imus, et collígimus ea? Et ait: Non: ne forte colligéntes zizánia eradicétis simul cum eis et tríticum. Sínite utráque créscere usque ad messem, et in témpore messis dicam messóribus: Collígite primum zizánia, et alligáte ea in fascículos ad comburéndum, tríticum autem congregáte in hórreum meum.

+        At that time, Jesus spoke this parable to the crowds: The kingdom of heaven is like a man who sowed good seed in his field; but while men were asleep, his enemy came and sowed weeds among the wheat, and went away. And when the blade sprang up and brought forth fruit, then the weeds appeared as well. And the servants of the householder came and said to him, ‘Sir, did you not sow good seed in your field? How then does it have weeds?’ He said to them, ‘An enemy has done this.’ And the servants said to him, ‘Will you have us go and gather them up?’ ‘No,’ he said, ‘lest in gathering the weeds you root up the wheat along with them. Let both grow together until the harvest; and at harvest time I will say to the reapers: Gather up the weeds first, and bind them in bundles to burn; but gather the wheat into my barns.’
