Matthias Clasen 8085b41074 GtkCheckMenuItemAccessible: Make work with model menu items
GtkModelMenuItem does not emit the ::toggled signal when a radio
item is activated, so listen for property notification for that
property. We still keep the ::toggled signal handler, in order
to not break other uses of check and radio menu items.
