Fixed language file import problem: https://www.howtoforge.com/community/threads/import-language-issue.70355

FS#3900 - Invalid home dir for shell users. Changed description from -Dir- to -Base Dir- to refelect that /home/username is appaneded to this directory.

- 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.

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

-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
