Set item color coding

For consistency with other item cards, the rarity of set items is now color-coded as well. This will make it much easier to transmute set items in the cube and also to see the rarity (value) of a set item at one glance.. When dropping the set items still appear in green font, so that you see it's a special drop. Thanks for DerpMinh for the suggestion :-) Here are some preview images: set-rarity-01 set-rarity-02
