tab hidden/shown event should give index of tab hidden/shown

[gregaton]

I'm currently using one controller to handle all my tabs (they are dynamically generated). In this case it would be very helpful to know which tab got selected when the shown/hidden event is fired.
For me the index would be fine.

All that's needed as far as I can tell is that the code for the tab directive after $scope.$watch('isVisible', function(value) { is changed from

$rootScope.$broadcast('tab.hidden');
...
$rootScope.$broadcast('tab.shown');

to

$rootScope.$broadcast('tab.hidden', $scope.$index);
...
$rootScope.$broadcast('tab.shown', $scope.$index);

These events are broadcasted only to child scopes of a tab, not from $rootScope. That was a bug.

If you wish to detect (in nightly or 0.9.26), do this:

<ion-tabs ng-controller="MyCtrl">
  ...
</ion-tabs>

function MyCtrl($scope) {
  $scope.$watch('tabsController.selectedTab', function(tab) {
    var index = $scope.tabsController.getTabIndex(tab);
    //dosomething
  });
}

<ion-tab> also has on-select and on-deselect expression bindings for you to use.

Documentation is a very high priority and will be coming soon!
