fixed ActionController to prevent having context and services in action data
fixed Descriptor to allow "packageDir" being set dynamically (todo: better api)
fixed ResultTypeListener to take care of :packageDir
fixed RedirectResultType to accept actionName parameter (instead of "action")
fixed ResultTypeService to use cloned instances of types (required to allow 'embeded actions')
fixed EmbedViewHelper: moved logic into helper instead of ResultTypeListener
