Implemented script-from-start for dumb interface.

This can be helpful when doing bugtesting runs.  Simply doing
dfrotz < input.txt > output.txt
will not put anything the player types into output.txt.  By using the
new -T flag, a transcript of the session is started immediately.  Using
the new -n flag, the name of the transcript file can be set at the
command line.
