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.

Stable 3.0.5 Fixes

See merge request !197

- 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.
