Big load of changes

- Added callback functionality for taskmanager tasks. You can launch
  a task and define a callback function to be run when the task finished.
  This requires activating the cronjob
- Added cron functionality: Add cronjob that calls the cron api every 5
  minutes to use it. (See cron.inc.php)
- Added eventlog
- Added missing translations
- Merged main-menu-login and main-menu-logout
