feat(modal): pass reason when opened promise rejected

[onjiro]

Pass rejected reason on opened promise rejected, like $routeChangeError event on ngRoute.
Give chance to handle error depends on rejected reason on opened promise.

I agree with onjiro.
This change might be able to handle the reason about rejection with "opened", like below.

$modal.open({
    templateUrl: 'myModalContent.html',
    controller: 'ModalInstanceCtrl',
    resolve: {
        resources: ['$resource', function ($resource) {
            return $resource('/my/resources').get().$promise;
        }]
    }
}).opened.catch(function (errorResult) {
    $window.alert(errorResult.statusText);
});

I think this is very useful.
