Subject: for more GUIes coherency, GtkOptionMenu is recommended instead of a
 combo if the user is selecting from a fixed set of options.

since both GtkCombo and GtkOptionMenu will be deprecated in 2.4.x in favor of
much better designed widget (see libegg's combo), we introduce a compatibility
layer that makes OptionMenu looks like Combo at API level to minimize changes:
- now, when using OptionMenu instead of Combo
- when new widget will come to live in gtk+-2.4.x
