---Returns a list of localized subclass names for a given item class. Item subclasses are the second level of hierarchy seen when browsing item classes (categories) at the Auction House: One-Handed Axes, Two-Handed Axes, Bows, Guns, et al for Weapon; Cloth, Leather, Plate, Shields, et al for Armor; Food & Drink, Potion, Elixir et al for Consumable; Red, Blue, Yellow, et al for Gem; etc. This function still returns valid information if the player is not interacting with an auctioneer.
