[development] groking ajax callbacks

[Peter Wolanin]

Augustin,

The #ahah element was (if I recall) added after the major changes to
the book module went in.  So The page I pointed you two predates its
existence (and is thus obviously incomplete).  quicksketch and
dmitrig01 tweaked the book module form to include #ahah later.  You
might be able ask them for some help with the docs.
