Bugfix in options settings

By setting an option like this:
<code>
 $scope.cropOptions.option = $scope.cropOptions.option || true;
</code>
will not take it if the option passed is FALSE. By setting like this it will:
<code>
 $scope.cropOptions.option = (typeof $scope.cropOptions.option == 'undefined' ? $scope.cropOptions.option : true;
</code>
