Changed apache_ispconfig.conf.master template to allow access to phpmyadmin and squirrelmail in debian.

Added: interface module web traffic statistics
Fixed: mail_traffic is now reported to master server instead of local
Fixed: GRANTs for slave server database user on master database

- Added deny directives to prevent direct access to the /var/www/clients and /var/www/domain.tld directories.

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.
