Changing the UI for [[Special:Specialpages]].

Changing the UI for [[Special:Specialpages]].
* Restricted pages are now with the normal pages (Special pages of a group are grouped together rather than split up on whether they are restricted or not [which does not matter to the user since they can use the page anyways])
* Restricted pages are still marked so the user can identify them. (CSS Class allows this behavior to be customized, default is to bold the link)
* New layout change. Rather than a poor table based column layout, using a dynamic CSS based one. This one uses floats and list items. With CSS disabled you get a single list. In 800x640px you get 2 columns, in 1042x860px you still get two columns, and in large screens like my 1280x1240px you get 3 columns. (770px width and below you get a single column) so this scales well no matter what screen size you have.
