LOGIC:
- if user is logged in, show the login information in the area
From now on we assume the user is not logged in:
- if it's no POST request, show the login form
- if it's a POST request, check the if the credentials are valid, if not, show the login form with error again
- if credentials are valid, redirect the user to the ``logged_in_url``
This probably can be done in a frame, too but the logged_in URL needs to redirect the top frame then.
JS on the fly validation: Can be done by simply setting the classes and ids and the host application need to provide
the JS for it.
