- new feature : use Apache authentication. If $conf['apache_authentication']

  is set true : if no user matches $_SERVER['REMOTE_USER'] in "users" table,
  PWG automatically creates one. This way, users can customize the behaviour
  of the application.

- template : new organisation of identification menu
  (category.php). Simplification is required for Apache authentication (no
  logout link even if user is externally logged in)

- new : usernames can contain quotes (required because Apache authentication
  authorized quotes in usernames)
