Put vlogger log directives in separate apache config file so they are available for the websites even if the controlpanel is not installed on the server.

- Fixed bug were the interface is enabled after an update on a server were interface = no selected during install
- Fixed a replication problem and made replication more fault tolerant.

- Chnegd installer to allow access from the slave hostname and IP address to the master database.

- Added some general php settings to config.inc.php

- Updated the user and database prefixes to use this storage.

- Improved installer and updater for multiserver mode. Modules and plugins were only configured if the selected service is available on the server.

No commit message

- Update server.ini during install
- Changed default vmail directory form /home/vmail to /var/vmail

Fixed some php warnings in update script that appear when a version without multiserver replication is updated.
