This PR replaces the separate admin views for unsubmitted, submitted and
confirmed statements by one common view. To distinguish the state, we
now display a colored badge in the changelist.
The default permissions for the `Standard` group are changed so that
normal users can continue to view statements they are related to when
these are submitted or confirmed.
Add `Link` model to customize the admin startpage from the admin interface. Also add block rendering of links.
