* if timeout is 0 it will show the message permanently
* removes the notification after a given (default: 5 seconds) timeframe
* based on work by @brantje
* provide JS unit tests for notifications

Currently if a user does not replace the .htaccess file with the new update this can lead to serious problems in case Apache is used as webserver.
