//  Location Feedback from the client side got a lot more complicated
//  since we need to support already exported sites as well.
//  The special treatment for exported sites could be removed in case we
//  use special versions for the globals during export.
//
//  How does it work now:
//  1) Check first level navigation (IFC: element has ID "navigation")
//    a) In case something already hilighted do nothing (i.e. we are on
//       a lower level because then the item is already hilighted when it
//       reaches the client).
//    b) Try to find the item in navigation which represents current page.
//    c) As APIhwdownload adds ".htm" to the pages check again if not
//       found yet - this time without suffix.
//    d) Startpages are renamed to "index.html" as standard web servers
//       recognize files with that name as "startpage". Therefore try to
//       find links within the navigation which point to "index.htm".
//       As for subfolders the navigation directly points to the corresponding
//       startpage hilight the navigation item with the shortest href.
//  2) Check second level navigation (IFC: element has ID "subnavigation")
//     -> The same steps as for point 1)
//
// ">
