- added admin_clients.php file for managing FroxlorClients
- added Multiserver-Menu
(unfinished, just base-layout for further developing, disabled by hardcoded setting)
- added 'isactive' for cronjobs so the admin can deactivate them (planned for 1.0);
- re-adding 'panel_diskspace' and 'panel_diskspace_admins' to install/froxlor.sql;
- show only 'logout' and 'froxlor update' in menulist when files have been updated and db is not up to date;
- bugixing success.tpl (closing <a>-tag);
