- Improved installer and updater for multiserver mode. Modules and plugins were only configured if the selected service is available on the server.

No commit message

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

changed the menu (hopefully now better to understand)
fixed some small errors in update-state

Monitor Module now has system state

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)

Added new table monitor_data for the core-module monitor.

- updated the debian installation instructions

- added server module for firewall and database.

Moved server modules and plugins to new directory and updated the installer to create the symlinks for the modules and plugins from *-available to *-enabled directory.
