Add Assumption's proper Matins hymn

"Surge! Jam terris fera bruma cessit" / "Arise! the cold blasts from
earth have receded", read from the reference engine's Sancti/08-15.txt,

+# The Assumption's own proper Matins hymn ("Surge! Jam terris fera bruma
+# cessit" / "Arise! the cold blasts from earth have receded"), read from
+# `Sancti/08-15.txt`'s own `[Hymnus Matutinum]` block (both Latin and
+# English) -- distinct from the BVM Common (CommuneM/C10), which has no
+# Matins hymn override of its own at all. Used throughout the Assumption's
+# octave (Aug 15-22), not just on the feast day itself: `Sancti/08-21bmv.txt`
+# (a representative octave day) carries `[Rule] ex Sancti/08-15`, meaning the
+# octave day's whole office -- Matins hymn included -- is the Assumption's
+# own, not the plain BVM Common's.

+    Surge! Jam terris fera bruma cessit,
+
+    Ridet in pratis decus omne florum,
+
+    Alma quæ Vitæ Génetrix fuísti,
+
+    Surge, María!
+
+
+    Lílium fulgens velut in rubéto,
+
+    Mortis auctórem teris una, carpens
+
+    Sóntibus fructum pátribus negátum
+
+    Arbore vitæ.
+
+
+    Arca non putri fabricáta ligno
+
+    Manna tu servas, fluit unde virtus,
+
+    Ipsa qua surgent animáta rursus
+
+    Ossa sepúlcris.
+
+
+    Prǽsidis mentis dócilis minístra,
+
+    Haud caro tabo pátitur resólvi;
+
+    Spíritus imo sine fine consors
+
+    Tendit ad astra.
+
+
+    Surge! Dilécto pete nixa cælum,
+
+    Sume consértum diadéma stellis,
+
+    Teque natórum récinens beátam
+
+    Excipe carmen.
+
+
+    Laus sit excélsæ Tríadi perénnis,
+
+    Quæ tibi, Virgo, tríbuit corónam,
+
+    Atque regínam statuítque nostram
+
+    Próvida matrem.
+
+    Amen.

+    Arise! the cold blasts from earth have receded,
+
+    And in the field are lovely flowers smiling,
+
+    For thee, O gracious Mother, bearer of Life,
+
+    Arise, O Mary!
+
+
+    Beautiful Lily blooming 'mid the brambles,
+
+    Death's haughty author thou alone didst conquer,
+
+    Plucking life-giving tree of fruits the fathers
+
+    By sin did not taste.
+
+
+    Ark of sweet wood not destined for ruin,
+
+    Holding the manna, whence springeth forth the power
+
+    Summoning forth the bones again arisen
+
+    From depths of the tomb.
+
+
+    Thou handmaid, faithful to the Ruler of hearts,
+
+    Thy flesh cruel decay could never touch,
+
+    Thy soul of Spirit partaking without end,
+
+    Hath winged to the stars.
+
+
+    Leaning on thy beloved, arise, go heav'nward!
+
+    Accept the crown with stars for thee bedecked,
+
+    List to the hymn thy children sing on this day,
+
+    Calling thee blessed.
+
+
+    Praise to the Triune Godhead everlasting,
+
+    Who hath caused thee, O Virgin, to be crowned,
+
+    And providently willed our Queen thou shouldst be
+
+    Also our Mother.
+
+    Amen.
