Can confirm Salverun does not need to be tracked. It is obtained through ~guranteed drops with weekly lockout

According to wowhead comments, there's a world object "Secured Shipment" that may contain the pets? Not sure if that also needs to be tracked; if so we'll need more hacky code similar to SPECIAL items. For now, I'll add the NPC drops as a primary source.

Edit: Moved to a separate issue, since I have no way of finding out what's the deal with it (or adding and testing the code).
