This adds extra code events:
Added controller_post_dispatch is similar to controller_pre_dispatch and has the instance of Controller and ControllerResponce in arguments.
Extension of ConrollerHelpers and Handlers become posible since they are called using auxiliary methods of controller and model.
Event controller_post_dispatch is added by extending all the controllers. Extension of all controllers is realised by extending autolader.
Feel free to request other handlers to be extandable.
To Kier and Mike: please, add this code events to the core and please, consider extension of regular Helpers. Mainly XenForo_ViewPublic_Helper_Message is very important.
