emit "ngAutocomplete:place_changed" with Google's "place_changed" event

[thiphariel]

I know there is already a PR about that (penghou620@10e8d9f) but I think this one has a different approach, I prefer get the sended result directly from the emit event than take it back from the scope.

// Simply get the directive result on this event
$scope.$on('ngAutocomplete:place_changed', function(result) {
    $log.info('Google's places results : ', result);
});

It's fate is in your hands \o/
