Author Common-of-a-Martyr/Apostle categories and St. Andrew's proper Matins psalmody

Two categories live-verified: common-of-a-martyr (from St. Ignatius of
Antioch, whose own office is entirely Common — also confirms
Common-of-a-Martyr-Bishop redirects to this same scheme, and that none
of its 3 Duplex+ saints has a proper antiphon of his own) and
common-of-an-apostle (from St. Bartholomew). St. Andrew authored as the
second saint-level proof, sharing the apostle category's psalm numbers
in every slot with his own proper antiphon text.
