Guidebook.tex catch up, Guideboon.mn bits

Guidebook.tex not tested.  The \, in the continuation of S_stone is
a narrow space in LaTeX.  It should be \hspace{ width of '(' } but
I don't remember how to measure something in LaTeX or TeX.

Guidebook.mn is getting two small changes:  I forgot about the
guideline that each sentence be on its own line.  Also, this adds the
fix for wide lines in the dungeoneers list although the reordering
accompanying a recent change might have made that moot (unless some
future reordering puts wide names on the same line again, assuming
that was the issue).
