Deeper integration of RapidMiner

It seems the next milestone is coming for RapidMiner integration for KNIME. Check the following screenshot:
As you can see some of the RapidMiner nodes (those that are only inputting and outputting ExampleSets) are generated and used in a KNIME workflow. The description is not yet good, it has to be improved, but it is possible to set the parameters, specify the roles in the configuration, and the icons are used when they are available. There are things to do, but I think this is a promising step forward. :)
