[glom] Use a custom Notebook-like widget instead of Gtk::Notebook.

[Murray Cumming <murrayc src gnome org>]

commit 65c72e4e16f41d73fa7827d7e53a1464d6055888
Author: Murray Cumming <murrayc murrayc com>
Date:   Mon Mar 7 23:35:23 2011 +0100

    Use a custom Notebook-like widget instead of Gtk::Notebook.
    
    * glom/utility_widgets/notebook_noframe.[h|cc]: A new class with an API that
    is as much like the Gtk::Notebook API as we need it to be.
    Unlike GtkNotebook, this has no frame around the page at the bottom.
    That was wasting space because the extra division was unnecessary when it
    fills almost the whole window anyway.
    * Makefile_glom.am: Mention the new files.
    * glom/mode_data/notebook_data.cc: Derive from the new class instead of
    Gtk::Notebook.
