Title: Add echoerr which outputs to STDERR rather than STDOUT for errors

If you apply this fix, and then pipe the output of the script to `/dev/null`, all regular echos will be sent to `/dev/null`, but all the errors will be sent to stderr, which makes sure you get notified about errors, and not the "OK's".
