Editing Module:Sandbox/VergirGive feedback

-- Test harness for the proposed Module:GameData prop-matching change.
-- Renders with {{#invoke:Sandbox/Vergir|test}}
--
-- Holds a copy of both the current and the proposed matching code, runs the
-- proposed one against Data:AbilityData.json, and checks that every existing
-- list in Module:AbilityTable/Lists still selects exactly the same abilities.
