~~~~~~~~~~~~~~~~~~~
- Added documentation (README only for now).
- Made ``AppsMiddleware`` raise a 404 error if no site matches the
current requests' host.
- Added a ``SiteMiddleware`` for using feincms3-sites without feincms3
apps.
- Fixed a bug where creating a root page without a site would crash
insteaf of showing the field required validation error.
- Fixed the ``verbose_name`` of the site foreign key (it only points to
a single site).
- Added a ``CanonicalDomainMiddleware`` which works the same way as the
middleware in `django-canonical-domain
<https://github.com/matthiask/django-canonical-domain>`_, except that
it takes the site from a previous ``AppsMiddleware`` or
``SiteMiddleware`` instead of from a ``CANONICAL_DOMAIN`` setting.
