Title: Fixed invalid return URL for absolute CGIPath

If the site’s ```CGIPath``` is an external URL, such as http://www.example.com/mt/, the Facebook login button directed the user to a page in which ```redirect_uri``` was set to http://www.example.com/http://www.example.com/mt/mt-comments.cgi?…. Facebook would display an error page instead of the authentication screen.
