* module event "ampere.view.changed" added to supported global event handlers.
this event gets triggered immediately after a new view was rendered (typically after stepping from one state to another)

* fixed : ng events (ng-click for example) triggering angular scope.$apply actions can now be infinite nested
* fixed : transition action results returning a (promised) function will be taken into account as redo function if the promise succeeds

* fixed : update method takes over current state values into the angular scope

* angular upgraded to version 1.1.4
