Remove tempering completely

As I see it there are a few problems. Tempering is more important than the item. This hurts the item hunt concept as a base item with good - great tempers is better than a 3GA item that missed on the tempers. The next part is the conditional affixes, which was the main problem with loot 1.0, is still present. Allbeit to a lesser degree as they are spread narrowed down to each manual. Finally and the most difficult problem is the perception. When the player has the agency to add the affix they want and can’t get it is a “feel bad”.
