Wiki Redirects and Page Renaming

Browse source 
Added the ability to rename existing pages.
[[!redirects Some Page Name]] redirects Wikilinks [[Some Page Name]] to
  the current page (assuming "Some Page Name" does not exist).
  Real pages trump redirects (though this may change, depending on 
  user feedback).
