Title: Session by event.

New enum ConferenceEvent (mixit12, mixit13), with const CURRENT giving current event.
All sessions are related to an event. A speaker is a member having a validated talk on current event only.
Sponsor are also related to one or several events.
Reset attendee registration (no tickets on current event). Previous attendee are given the new badge PreviousAttendee.

No GUI rework. Some screens, now empty, may need some editorial content (list of current sessions is empty for example). But as this PR is becoming really big, I push it now for review.

We can merge it, but we won't deploy it now.
