Fix bug that caused ajax-request to override values written to the session

Authentication/Session.php and its Subclasses do not have a open/closed -state
anymore. Read will refresh the session, write will always write the changes,
and opening/closing will be handled internally.

Fix messages in ConfigController

Store messages in the current user session to be able to fetch messages from
other controllers, so that the use can be redirected back to the index, instead
of staying in the original action

send from everywhere and there is no need to consider consquences of
redirections.
