propers: Benedictus antiphons for June's sanctoral entries (16/16)

11 authored fresh (Ss. Marcellinus/Peter/Erasmus, Ss. Primus and
Felicianus, Barnabas, Anthony of Padua, Basil the Great, Ss. Vitus/
Modestus/Crescentia, Ss. Mark and Marcellian, Ss. Gervase and Protase,
Paulinus of Nola, William Abbot, Leo II), 5 corrected (Ss. Basilides/
Cyrinus/Nabor/Nazarius, the Nativity of St. John the Baptist, Ss. John
and Paul, Ss. Peter and Paul, Commemoration of St. Paul -- each
confirmed sourced from the Roman rite's raw [Ant 1] rather than a real
Monastic 1617 rendering, same pattern as every month so far).

Barnabas needed the same register fix as Matthias (Matt 19:27ff, same
verse): the source's own English existed but read jarringly modern
next to everything else, reworded to match and marked draft.
