- improved the node sorting

- PEAR-ification of Drupal by claw: you can now host Drupal on a wide
  range of databases including MySQL, PostgreSQL, MSSQL, and others.

  For additional information and an 'how to upgrade', check the mails
  sent to the mailing list.

- improved the tracker.module so that it shows all the recent comments
  instead of all recent comments to recent nodes.

- a batch of updates, including some experimental changes to the moderation
  of comments and nodes.

- added a new tracker.module (everybody kept nagging about the missing
  "your drupal" feature). Tracker.module will be improved and expanded
  during the process.

- renamed a link in user.module
