Make setDirty more clever about ember-validated-form

[czosel]

Hi @makepanic, that would mean that focussing and un-focussing an input element without changing it wouldn't mark it dirty, right? I think that's not great for UX - for example, you wouldn't immediately see required field validations anymore.

I guess you're right that it doesn't make sense for all forms.

For our case we have a form that takes focus and only validates when changing the value or once it's submitted. Required fields are visually marked and simply focus/blur isn't triggering the validation.

I guess we can close this issue as it's possible to create a validated-input component and simply overwrite the default setDirty implementation to use model.isDirty.

Alright - i'll leave the issue open for a bit anyway. If there's more demand for something like this we could consider adding an option.
