Fixed a Bug in Centos 7 were php-fpm uses sockets while mod_proxy_fcgi in centos 7 does not support that yet.

- Fixed: FS#3710 - Bug with PHP-FPM configuration since 3.0.5.4 Patch 4
- Fixed wrong function calls in system lib.

-Added a new option "Network Filesystem" under System > Server config > Web to toggle on / off the _netdev option for the bind mounts in /etc/fstab

Note: The mod_proxy_fcgi that ships with CentOS and Ubuntu does not support sockets yet, so all php-fpm connections are done by IP.

- Added warning in the interface when a path for a shelluser is set that is outside of the website docroot.
- Added security settings feature to allow the root user of a server to control most aspects of whet the admin user of the controlpanel is allowed to do in system settings. This is especially useful for managed severs where the ispconfig admin user and the root user of the server are different persons.

Revert "Fixed: FS#3581 - Website unaccessible under some circumstances when using seo redirection *.domain to www.domain"

This reverts commit 5742e4c9.

Fixed: FS#3581 - Website unaccessible under some circumstances when using seo redirection *.domain to www.domain
(only for apache2, nginx still to do)

- Changed vhost.conf.master as php-fpm was not working after commit "5a6670bd".

Fixed: db user not created in mysql user table if password is stored in cleartext (ISPConfig < 3.0.3.3)
Fixed: db user not created on update if status not changed (e. g. on using resync tool)

- backups: plugin checks mount point of wrong backup directory (e.g. /var/backup/web10 instead of /var/backup).

- Make sure full cron jobs are written unchanged; with the previous version, a cron job like "cd /var/www/example.com/web/ && /opt/php-5.4.23/bin/php shopware.php /backend/cron" was changed to "/var/www/clients/client1/web1/cd /var/www/example.com/web/ && /opt/php-5.4.23/bin/php shopware.php /backend/cron" which of course does not work.

Changed web folder permissions in nginx setups from 711 to 751 to avoid (false) permissions warnings in log files.
