Ralph Castain 0140ff048d Now that we have an "isolated" PLM component, we cannot just let rsh silently decline to run when it cannot find a launch agent - if we do, then we will -always- run on the local node. So if the user specifies a launch agent and we can't find it, then generate a pretty error message, report a fatal error back to the component select, and exit out.
This required modifying the mca_component_select function to actually check the return code on a component query - it was blissfully ignoring it.

Also do a little cleanup to avoid bombarding the user with multiple error messages.

Thanks to Patrick Begou for reporting the problem
