Send error to stderr

Why do you want to send an error when falling back to default node address?
It works, why returning an error?

[mmuman]

It's not part of the proper output, it's a warning. If you want to parse the output it's really annoying.

./sikaj diffi
and
./silkaj diffi -p duniter.org:10901
give 0 to echo $? output.

I don't understand the usage of this modification.

[mmuman]

I meant parse stdout. From a script or something else.
Like I want to use it with Argos but it will use the warning as menu title instead of the intended name...

Sending stuff to stderr has nothing to do with returning an error code to the shell, btw.

Ok. Let's merge.
