[IMP] event and event_* modules: onboarding improvements

event:
- added tip
- default subscription/reminder/thanks templates for registrations are now using
the reply_to defined on the event
- fixed check of available seats: use seats_availability field, unlimited events
should never trigger the constraint
- added a sequence on scheduled emails on events
- config: wording improvements
- various improvements in event, registration, event_mail and event_report views

event_sale:
- removed override of seats_max: should not depend on available seats in
tickets. Indeed you may have less available places than the sum of seats for
each ticket type, for example if you have 0-10 VIP and 0-20 Standard tickets
for a 20-seats event.
- removed a duplicated view override
- added a seats_availability field on tickets, same meaning as on event.
- improved event form view: registration tab is now replaced by the tickets tab
when tickets are used

website_event:
- better management of sold-out event in the front-end, when doing registrations

website_event_sale:
- removed register link on the event kanban view. There is no need to to from
the back-end to the front-end from the kanban view. The published button on the
event form view already allows to go to the front-end view on the event
- better management of sold-out event in the front-end, when doing registrations
- fixed a template that was in customize and should not

website_event_track:
- wording improvements
- small improvements in the front-end of tracks
