----------------------
-- Corrected another bug in BuildDo.vi: In case of a return message the inputs of the receiver message were used to be connected to the Sender Action vi and not the outputs
-- Larger modifications to the ReturnMsgPanel: From now on he calculates which messages are possible with the sender methods connector pane. Everything else will not be shown to the user. In a next stel the expert mode has to be implemented.
-- Exchanged some deprecated VIs I used to check if a variant is an error cluster
