There are a few problems with the page information screen:

a) External and internal outgoing links aren't separated. We can have them in one list (outgoing links) but external links should be postfixed with the external link icon (like they are in the page content).

b) Internal links are displayed the same whether or not they exist. If the destination page does not exist we should print it in red with a + sign etc (again like in the page content) and then link to the create page not the display page.
