Tweaked ore bonuses

Some are to make some real world sense (zinc ore has some sulfur - sphalerite, orichalcum is historically referred to some sort of copper/bronze alloy so it'll drop bronze dust, etc.)  and some are for balance purposes (adamantine + atlarus = tartarite.  Since this is the highest tier material for any and all equipment, it's best that these ores don't receive too many bonus dusts).
