The dependency turned out to be that gnc-main-window registers the
book-open/close hooks for restore/saving global state -- even state
like reports, (which, unfortunately, are not per-window or even
per-book, but global,) -- in its class-init function (seems like a
pretty strange place to me).

I found a better solution than pulling gnc-main-window into gnome/.
First, I'm going to register the open/close book hooks during gui
init, not class-init.  

Second, I'm going to distinguish between book-level persistent data
and window-level persistent data.  Currently, the only book-level
persistent data are guid and the reports.  Book-level persistence will
be handled from /gnome/ and window saving/restoration will stay in
gnome-utils.
