window manager tries to delete it, so no callback is needed for the
"destroy" or "delete_event" signals (grabs are, at least in GTK+ 1.2.7,
removed when a widget is destroyed, and there's no need for the destroy
callback to destroy the widget itself; the delete event handler *could*,
for example, pop up a dialog box saying "Do you really want to close
this?", and allow the user to back out of the operation, but there's
no unsaved work that would be lost by closing the window, so there's no
point in having a delete event handler that does that).

summary.c now provides a struct of info (see summary.h)
Changed the name of the summary dialogue callback (hence the change
in menu.c), and added a close button to the dialogue.
Moved #include <gtk/gtk.h> out of print.c and into prefs.h where it
was needed for GdkColor.
