  This adds session support for anonymous users and fixes a bug/typo.

    1. changed rid for user #0 from 0 to 1 (rid 1 == anonymous user) to make
       inner join work.

    2. replaced "if ($user .." by "if ($user->uid .." because now $user is
       always set (my previous change probably caused this).

    3. db_next_id("user_uid") -> db_next_id("users_uid");

  I repeat:

  "This adds session support for anonymous users and fixes a bug/typo."

TODO:

- Does our XML feeds validate with the charset changes?

  Kjartan.

  This update requires some database changes so make sure to run update.php.

  In addition, I have updated update.php so it makes the corresponding
  changes for MySQL users.

- Applied modified version of Al's "block delta" patch.  I left out the
  blogroll feature as I think it would get very confusing.  I don't mind
  to add it but it need some thought and documentation as it somewhat
  conflicts with the existing cloud module.

  These changes require you to run update.php.

- Made sure that update.php enables the newly created admin module.
  This should fix the other half of bug #1508.
