Have FieldEditor update on ElementUpdatedEvents; Require match NamedEvent!

- It would update if an AttributeChangedEvent was received, but not an
  ElementUpdatedEvent!

- If you have 50 fields and 50 editors, then every one was updating
  whenever an event arrived? Filter by the field that actually changed?
  Does this break something?
