[SUGGESTION] Don't load catalog_items if amount is 0/-1

Please add extra SQL check for loading catalog_items. There are cases, when item is not intended for selling, but deletion/moving item to different page breaks integrity with Habbo's Furnidata, so it will be much easier to keep item in database, but just hide it.
Creating a new field in db table may break compatibility, but adding an extra condition in sql should be safe.
