Title: Show registration buttons only if adhocracy.allow_registration is set.

Registration buttons in header and overlay are shown only if
registration is allowed for the adhocracy installation
and an appropriate message is shown for each case.
Otherwise, the registration button leads the user to the registration form, resulting in HTTP 403 when clicking on register.
