Stella Rouzi 4289f699ac Add enabled to event_schedules
To show scheduled events that have been cancelled/withdrawn as 'cancelled', and consequently also show when an event is their replacement.

admin/schedules#show does not show events that were scheduled and then cancelled/withdrawn, however a record in event_schedules exists for those events, but event_schedule.enabled = false
