Reforge Bench suggestions

Would suggest some additions to the reforge bench to make it more fun, functional, and fair:

- Allow different types of the same base to be used. Either the ilvl or clvl of the three items are averaged to determine the final result. So, if you use a mace of clvl ~10, ~20, and ~30, the resulting mace would be clvl level 20, averaged down or up to the closest base near level 20. This removes the restriction of using 3 identical maces.

- The modifiers should combine in a way that makes the bench feel more meaningful. If I have a life mod on each item, but it's a lower tier mod (+7 - 15 life), the resulting item could have a higher life tier mod (+80 - 99 life)

- Allow the rarity to upgrade occasionally. So, reforging 3 magic items could sometimes create a rare item. Possibly 3 rare items could sometimes create a unique with the rates of a chance orb.
