There is no extra ``/login`` and ``/today`` URL anymore. Login form and
today's overview are both rendered on the new front page at ``/`` depending
on the user's login status. If the user is logged in all the exercices
performed today are shown, otherwise a login form is represented. The POST
login method is also handled at ``/``.

Please note the old ``/login`` POST won't work anymore! GET is redirected
to the front page from the both old URLs. Please change your URLs, if
necessary.

Thanks to WF for this change request.
