Multiuser and MQTT passwords

[jpmens]

wenn es mehrere devices per user gibt und dort verschiedene passwörter angegeben werden klappt der MQTT connect nicht, weil im otrc nicht das erste sondern die verschiedenen Passwörter stehen

@ckrey I'd appreciate you re-testing this which I think works. (Famous last words.)

The password configured for the first found, say, jane (case insensitive test) will be used as subsequent password for all of Jane's devices.

I does work well
