Robotics Systems Types

A minimal informer/listener example for the supported languages would already be helpful that just shows:

* how to register / configure converters
* the usage of RST types
* the usage of typed RSB objects with these RST types

This could become a section within the RST manual as there is also already a _Developer_ tutorial:
http://docs.cor-lab.de//rst-manual/trunk/html/index.html

However, developer does not mean usage here. Hence, we would need a _User_ tutorial.
