* reword various texts in website_event to avoid references to a sell
or checkout process as website_event does not handle sakes;
* if there is only one ticket available, propose to take one by default.
Display Register Now instead of Order Now if tickets are free. Display
an error if the user chooses no tickets in its registration.;
* link in cart for event tickets redirects to event, not product;
* confirm attendees only at invoice payment;
* improve wording, use schedule instead of agenda.
