(InitUI): fixed Configure binding to use correct namespace for OPT

	(InitUI): fixed Configure binding to use correct namespace for OPT
	(EvalSocket, EvalSend, EvalAttached): cleaned up to require that
	they accept only one arg as the command string to be evaluated.
	Prior behavior left some ambiguity as to what was eval'ed where.
	EvalOther, EvalSlave may need some sanitation as well.
