[gtkmm] Gtk::Widget: Add new API

[Kjell Ahlstedt <kjellahl src gnome org>]

commit 6ff7774b3a5c4ae73875bf0228fe0d67b5edf175

    Gtk::Widget: Add new API
    
    * gtk/src/widget.[hg|ccg]: Add set/get/property_focus_on_click(),
    set/unset/get_font_options(), set/get_font_map(), queue_allocate(),
    get_allocated_size(). (unset_font_map() is not necessary. FontMap is unset
    with a set_font_map(Glib::RefPtr<Pango::FontMap>()) call.)
