Module configuration now takes place in module detail view and does no
longer pollute our config tabs. Modules are now able to provide a bunch
of own config tabs, we don't really care what they use them for.
This will make the code of the ConfigController way easier, as messages can be
send from everywhere and there is no need to consider consquences of
redirections.

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
