In python 3 dict.items do not return a copied list so we force a copy
to avoid changing the global dict while iterating over it

Rename the unicode methode of ReturnUnicode in cas.py to prevent clash in spnhinx autodoc with unicode type

As it seems to not work

Add a federated mode.

When the settings CAS_FEDERATE is True, django-cas-server will offer to the user to choose its CAS backend to authenticate. Hence the login page do not display anymore a username/password form but a select form with configured CASs backend.

This allow to give access to CAS supported applications to users from multiple organization seamlessly.

It was originally developped to mach the need of https://myares.fr (Federated CAS at https://cas.myares.fr, example of an application using it as https://chat.myares.fr)

Also fix some unicode related bugs

hence, the behaviour is consistent between python2 and python3

an that this is the OS travis use. cf https://bugs.python.org/issue23063
