[Rock-dev] Roby: Event-Emitting from ScriptingEngine

[Christoph Mueller]

Another feedback for a current bugfix in the roby sources.

method(:superior_method)  do
    # service composition
    self.service.script do
         # some executes and polls
         ....

         emit :success
    end
end

(Information for the other rock developers)
* This failed some days ago due to a missing method error for 'event' for
:success.

I think its working now, but executing this method via the roby shell results in
another error:

This worked in the past because we used it very much in the avalon planners.
