propers: Benedictus antiphons for May's sanctoral entries (13/13)

10 authored fresh (Athanasius, Monica, Stanislaus, Ss. Nereus/
Achilleus/Domitilla/Pancras, Boniface, Ubald, Peter Celestine, Urban I,
Eleutherius, John I), 3 corrected (Ss. Philip and James, John Before
the Latin Gate, the Apparition of St. Michael -- 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).

Urban I, Eleutherius, and John I (all late May) needed 2038 to find a
year not swallowed by Ascensiontide/Pentecost/Trinity/Corpus Christi
in some combination -- the latest year needed yet.
