- Renamed "hostname.conf" to "setting.php" (cfr. "setting.module").
  Note that - when upgrading - you have to rename all your existing
  configuration files to reflect this change:

     yourdomain.com.conf -> yourdomain.com.php

  By default, i.e. if no configuration file is found, setting.php
  will be used instead.  Using the ".php"-extension will fix most
  configuration/security issues with .htaccess-files ...

- Removed some dead code from forum.module.
