pf-notification-drawer cannot take an object for notificationGroups

[benjaminapetersen]

Its pretty common to be able to pass an array or an object as an arg, but the pf-notification-drawer will only accept an array:

scope.$watch('notificationGroups', function () {
 var openFound = false;
 // this line demands that notificationGroups be an array :(
 scope.notificationGroups.forEach(function (group) {
   if (group.open) {
     if (openFound) {
       group.open = false;
     } else {
       openFound = true;
     }
   }
 });
});

Using a utility like angular.forEach would provide some helpful flexibility & eliminate the need for glue code to swap objects and arrays back and forth.
