Reminders user interface
We should offer reminders for favorites talks; a reminder should automatically be created when a talk is marked as favorite, and it should be scheduled n minutes before talk start. Automatic creation of reminders should be opt-in and the reminder time should be configurable.
We could also offer multiple reminders, IncidenceAlarmsModel can be used for this. IMO it is an overkill, and we can just delete IncidenceAlarmsModel. But not sure...
