Output using stdout and stderr respectively

[melwil]

As of now, all output from the init.d script is output to stdout, which means that "OK" messages gets put into the same logs as "ERROR".

This leads to some problems, as we've started to send output from such scripts on email to the maintenance department, and getting an email with e.g. "saving world to disk" all the time. Currently there's no good way to avoid getting the good messages on mail and still receiving the actual errors.
