Favorite class

Changed the navigation.

I've gotten some emails from users with the request of only show the spell from "that" class. But, I haven't really seen a use for it when you so easily can use the filters. But I decided to go ahead with it any way.

Under the menu Class you will find the "class exclusive" spells and under the menu Spells you will find a subpages with classes which have "class available" spells. I hope some of you will find it useful.
