Data port types should support real class definitions

[franzlst]

Right now data port types support all primitive python types (int, string, list, dict, object etc.). (User defined) classes are not supported right now.

Please see also what has been commented in #389. A general base class for arbitrary parameter classes/types would be a good step to do this enhancement here and the one requested in #389.

@Rbelder: I think you misunderstood @sebastian-brunner
@sebastian-brunner: I think this is already possible. Just specify the full qualified name of your class (e.g. rafcon.core.states.execution_state.ExecutionState) and make sure the package (in this case rafcon is within your PYTHONPATH)

@franzlst that should work what your are describing because of the locate command should do this.

I never have used it this way but that would also fall into the config master thing of issue #390, I think.

Next question is also if this behavior is a feature or a bug. What means do we really wanna have such a implicit behavior in RAFCON as a feature? I would prefer to have something more explicit like a related check with the imported classes of the script or something like this.

@franzlst: yeah great, this already works :-)

But you are then only able to open a state machine when you started rafcon with the correct environment. Probably we should only throw a warning and let the user open the state machine nevertheless.
