Bunch of updates...

I have installed a new certificate on the secure side of XaoxNet so you shouldn't need to install a certificate authority.  I have also updated Drupal to 6.28 for a security fix and update RoundCube webmail to 0.8.4 as a general upgrade.  RoundCube now has a plugin that allows you to sync your Google contacts.
As always, let me know if you have any trouble.
