Display validity when model is $touched, not when $dirty

[wolfika]

Consider this element:

<input type="text" name="subject" id="subject" ng-model="message.subject" required />

Current behaviour: clicking the field and then leaving it does not trigger validation because the model is $pristine.

Expected behaviour: regardless of being $pristine, the validation display should trigger when the model becomes $touched. I think it would be more logical to display validity status after entering and leaving the input.

See how Angular Material, a popular Angular.js library implements the described behaviour. (scroll down to Errors section to see a required field, and click into it, then out of it.) https://material.angularjs.org/HEAD/demo/input

I love it; that's a great idea! Fancy whipping up a PR for me?
