List of all pages for navigation

Issue #3234 duplicate
created an issue

It would be nice to have all the pages in the wiki automatically listed (sort of a title index). Github has this functionality as 'project_name/wiki/_pages'; the 'pages' tab in the wiki links to this. Listing this all in the home page is usually tedious: If you create a page by linking through another page, you will have to go back to the home page and update it there as well.
