Merchant data now includes non-money currency collection... i.e. Epicurean Awards.

Since for some reason we aren't actually getting the itemlink for the currencies, we are collecting the currencies ids by collecting finding out what currencies a vendor takes and storing the id, localized name and icon name. In the item info, we store the localized name and the texture (excepting the path elements, they should always be the same).
