Support to scroll to a particular item

[marcelotavares]

In previous versions there was the vsScrollSetting attribute that had the scrollIndex property to go to a particular item. But this feature was removed in newer versions and there is no substitute for it.

Proposed solution:

                    $scope.$on('vsScrollToItem', function(event, index) {

                        if(scrollPos=='scrollTop')
                            $scrollParent.scrollTop($scope.sizesCumulative[index]);
                        else
                            $scrollParent.scrollLeft($scope.sizesCumulative[index]);

                    });
