That fallback sets the redirect URL to itself (so it can process the login
token then return gracefully to the client). This would make it pointless to
ask the user for confirmation, since the URL the confirmation page would be
showing wouldn't be the client's.
If an error happened while processing a SAML AuthN response, or a client
ends up doing a `GET` request to `/authn_response`, then render a
customisable error page rather than a confusing error.
* Give `notif_template_html`, `notif_template_text` default values (fixes#6960)
* Don't complain if `smtp_host` and `smtp_port` are unset, since they have sensible defaults (fixes#6961)
* Set the example for `enable_notifs` to `True`, for consistency and because it's more useful
* Raise errors as ConfigError rather than RuntimeError for nicer formatting
Turns out that figuring out a remote user id for the SAML user isn't quite as obvious as it seems. Factor it out to the SamlMappingProvider so that it's easy to control.
Generally try to make this more comprehensible, and make it match the
conventions.
I've removed the documentation for all the settings which allow you to change
the names of the template files, because I can't really see why they are
useful.
