/*
	Modifications (last one on top):
		20120830 - WVR: The Dialog class was used to get general info on the DLL. This
						had a big disadvantage: the complete dialog was loaded, just to get
						some data and then it was deleted again (without ever showing the dialog).
						The ProtocolDll class solves this.
						The functions to get the name(s) and icon were removed from the two other classes.
