Resolve a queue row: approve the suggestion, reject the record or link it to a game

Body: {"action": "approve|reject|link", "game_id": 123, "edition": "deluxe"}. edition is optional (standard, deluxe, gold, goty, ultimate, bundle; not with reject): CheapShark records whose title does not reveal the edition stay unlisted until one is chosen here. Writes match_override (updates it if the record was decided before) and resolves the row.
