Actions supported for GailMenuItem

["Padraig O'Briain" <Padraig Obriain Sun COM>]

Five actions are proposed for GailMenu; these are
select, deselect, toggle which are inherited from GailItem and
activate and activate-item.

I have looked at these and I think that the only action we should
implement for a menu item is activate.

select
======
The select signal is generated when a menu item is selected. This can 
be done by using the AtkSelection interface on the menu to which the menu
item belongs.

deselect
========
The deselect signal is generated when a menu item is deselected; normally
another menu item is selected in its stead. Deselecting a menu item can be
done by using the AtkSelection interface on the menu to which the menu item 
belongs.

toggle
======
This signal is not used for menu items.

activate_item
=============
This signal is emitted only in the function gtk_menu_item_activate_mnemonic().
This function is the signal handler for the "mnemonic_activate" signal. The
signal is emitted by a call to gtk_widget_mnemonic_activate() which is called
from gtk_window_mnemonic_activate() which is called from 
gtk_window_key_press_event().

I do not claim to undderstand exactly what is going on here but it does not
seem to me that the activate_item signal is one for which we need to define
an action.
