Subject: [PATCH] [IMP] website_event: Label 'Participating' on frontend

On the event page and on the event list page on a website, add a
label "participating" for the logged users that are participating
to the event to avoid mistakenly double-subscribing. But we don't
hard-prevent it, because it should still be possible to subscribe someone else.

Small improvement: The portal group in general settings was hidden. We set it
visible because it contains some useful options like 'Allow external users to
sign up'
