/auth/services now returns the redirection URL instead of pointing
directly to the service.

Added support for an activation webpage and renamed dialog config param

LDAP login now returns status codes 200/401 instead of using

These URIs should not be requested if user does not successfully join a

If user is successfully logged in, store authentication in security context

different sessions and users.
It can be used to access current users (ARSnova)-session and user object.

This bean holds user and session object of the current user after he

Added two simple URIs to get a JSON representation of the referenced

It is possible now to simulate LDAP login by requesting login page manually
but it needs some more internal changes to do all needed stuff for a real
ARSnova login.
