CVS commit by waba: 

* Make sure to save a page in the right history entry
  (first save, then advance to next entry, not the other way around)

* When navigating via the Navigator class, the last status of the old page 
  was not always saved in the history (missing call to updateCurrentEntry)

* Fix a small problem where URLs weren't found in the treeview because the
  URL has changed due to redirection and a problem with correctly highlighting
  an item when it was the current item already. (subtle difference between
  current item and selected item, sometimes there is no selected item but
  still a current item)
