populate insight.c

Move enlightenment and conduct from cmd.c to insight.c.  Also move
vanquished monsters plus genocided and/or extinct monsters from end.c
to there.  And move the one-line stethoscope/probing feedback for
self and for monsters from priest.c to there.

Achievement feedback has been overhauled a bit.  When no achievements
have been recorded, the header for them (after conducts) won't be
shown, and when at least one has been recorded, make the prompt for
asking whether to disclose conduct be about disclosing conduct and
achievements.  Also, describe achievements in the Guidebook.

I ran out of gas before updating Guidebook.tex; it will catch up to
Guidebook.mn eventually.

Some of the MS-DOS Makefiles haven't been updated yet so linking
without insight.{o,obj} will break there.
