Guidebook tweaks (mainly DUMPLOG)

In the sysconf section, "the following options affect the score file:"
had some score options and then several non-score options.  Change to
"following four options" which reads a little strange but is precise.
Some other inserted line after those four options describing what
follows would read better but the stuff that follows is essentially
random based on the order that support for them was implemented.

Guidebook.mn:  the 'placeholders' for DUMPLOG file name substitution
had the description column line up but the proportional font for the
'%x' column looked bad.  Force fixed-width font there.  Also add some
indentation.  I wasn't sure whether '.in' should in inside .PS ... .PE
or outside.  The final result looks the same either way.

Guidebook.tex:  the new LIVELOG entry was accidentally placed after
the \elist line when it should come before that.  (Not tested.)
