Title: Adding a "validated" event

There are certain situations where the developer may want to see a "validated" event, rather than just relying on the change event triggered by model.set. For example:

1. You have a form field tied to validation. It currently has a valid value.
2. The user changes the field to an invalid value, triggering an error from validation. The model has not been updated, however, because validation fails.
3. An error message is displayed to the user.
4. The user changes the field back to a valid value, and you want to listen for an event to remove the error message. You cannot use the change event, because change will not be fired (the new value supplied by the user is the same as the old one that is still on the model).
