The "changed" error, and the failure to update the choice of link-layer types
or the monitor mode checkbox, are a consequence of connecting to the "changed"
signal of the child of the GtkComboBox when treated as a GtkBin, rather than of
the GtkComboBox itself; I fixed that in r36837.
The "activate" error, and the inability to type in the box, is a consequence of
creating it with gtk_combo_box_new_text() rather than
gtk_combo_box_entry_new_text(); I fixed that in r36838.
gtk_combo_box_entry_new_text() is itself deprecated, according to
http://developer.gnome.org/gtk/stable/GtkComboBoxEntry.html#gtk-combo-box-entry-new-text
but they don't say what it's deprecated in favor of. I'm *guessing* it's
deprecated in favor of gtk_combo_box_text_new_with_entry(), but that's not
supported until GTK+ 2.24, so, to use it, we'd have to do more conditional
wrapping. We use gtk_combo_box_entry_new_text() in a number of places.
