Title: Make TimelineEvent.end_date a nullable field

The field is allowed to be blank, and thus Django does not require that it be filled in; however, in the database, is it _not_ a nullable field, so the database _does_ require that a value be set. This difference in handling between Django and the database engine creates an `IntegrityError` when events are saved without end dates. This change removes that problem.
