Mirrors the Druid mana bar for the CoA Necromancer (class token
NECROMANCER): the main power bar shows the active power type while a
second bar shows the other one, so mana and runic power are both
visible at the same time. Adaptive — recolors to whichever resource it
is currently showing, so it works regardless of which power CoA treats
as primary. Off by default; toggle under Player bars (auto-hidden for
non-Necromancers).
CoA's 3.3.5 client returns spellId as the 11th UnitAura value (stock 3.3.5a
stops at 10). The scan loop now captures it and the whitelist/blacklist match
on name OR spellId. The filter 'add' box accepts a numeric spell ID (stored as
a numeric key so it matches UnitAura's spellId) and the list view resolves IDs
to 'Name (ID)' via GetSpellInfo. Fixes ambiguity from name-only matching where
CoA custom spells share display names across ranks/variants.
