#130 mged journal command needs option to save command output

[Tom Browder]

Currently the mged journal commands writes the user inputs to the journal file but it does not write the mged responses. A work around is to use mged from the command line and capture output, but that is not always satisfactory. A user option to mged journal (e.g., -r or --response) to also output the mged responses could be very useful in replaying or recovering from modeling errors.

Sounds like a good idea to me. It could even write the output prefixed with # comment characters so that it would still source correctly as a tcl script. If you look into implementing such a feature, it might work just by registering a logging hook (iirc, bu_log_add_hook()) and then writing the output to the file as it prints or buffering and then writing after the command completes or similar.
