- possible sql injection in monitor sys_state

- Made sure SQL backups from servers that differ from the server where the website is on can be restored. A download of the backup is not possible in such a case, therefore I hide the "Download" button.

- SSH users cannot be deleted if the web site uses PHP-FPM ("userdel: user ssh_test is currently used by process 2890"). Fixed this by stopping PHP-FPM before user deletion and starting it again afterwards.

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

- Changed tform_actions.inc.php to always provide oldDataRecord array for updates even when dbhistory = off.

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

- Fixed a problem with restart of services due to the fact that Ubuntu has upstart and systemd installed, but only upstart is working without errors.

-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

- Improved postfix SSL configuration to protect against poodle attack.
