The DEBUG mode by default is a temporary choice to have the users
beginning with Authentic 2 and using the development server not be
disappointed by the static files not served.
The Django Debug Toolbar is a dependency in the DEBUG mode.
django-registration is badly maintained currently, a fork exists named
django-registration2 but it is incompatible with django-auth-openid as
it changed some url internal names. For now we must consider
django-registration an internally distributed dependency. The copy in
authentic/vendor/registration/ should be updated regurlarly.
