Respect "menus_have_icons" property in GTK+

The default value is planned to be changed in the next minor update to
Gtk+ (2.28), hence we need to read this dynamically now. We also
added a helper-function to easily read a gconf bool.

Note, as a bonus feature I also added support for
"buttons_have_icons".
