Book Merge committed to HEAD

[Derek Atkins]

Hi,

I just committed Neil's book-merge code to HEAD.  A couple of notes:

1) you will need to "rm src/engine/.scm-links" in your build tree to
   get this to build properly.

2) There are still a bunch of bugs in the code.  I started with an
   empty data file and ran the File -> Add Hierarchy menu item.
   It showed me the "choose a currency" page but the page was empty.
   Then when it jumped to the merge druid I got the following error
   on my terminal:

   Gtk-CRITICAL **: file gtkwidget.c: line 1428 (gtk_widget_show): assertion `GTK_IS_WIDGET (widget)' failed.

3) This code (the druid in particular) will need to get ported to the
   g2 branch.
