Fixed some bugs and improved the RAID - monitor
Fixed the user count in the monitor
The monitor now monitors the rkhunter - log too
The monitor now deletes the old data AFTER writing the new one, so there are always data in the db

It is now possible to add "navigation-text" without links (actions) to the left navigations-side of the template (needed by the monitor module to add the server-dropdown)

- Fixed bug with maildir creation in mail plugin.
