Add $stateChangeComplete event

[donaldpipowitch]

Small feature request: Could you add an $stateChangeComplete event, which is triggered after $stateChangeSuccess and $stateChangeError? Analogous to the promise API: then, catch and finally. Most APIs for async operations have a similar style.

Quick hack for now (in case anyone needs this):

angular.forEach([ '$stateChangeSuccess', '$stateChangeError'], function(event) {
  $rootScope.$on(event, function(event, toState, toParams, fromState, fromParams, error) {
    // do stuff here...
    // error param is undefined for $stateChangeSuccess
  });
});

state events are going away in 1.0 so closing this.
