datepicker $setValidity $error does not follow convention naming

[emouawad]

In datepicker.js
ngModelCtrl.$setValidity('date-disabled', !date || (this.element && !this.isDisabled(date)));

$setValidity(validationErrorKey, isValid)
validationErrorKey: does not follow convention

The validationErrorKey should be in camelCase and will get converted into dash-case for class name. Example: myError will result in ng-valid-my-error and ng-invalid-my-error class and can be bound to as {{someForm.someControl.$error.myError}} .

You're right that should be edited.
