Actions for GailButton

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

According to 
http://developer.gnome.org/projects/gap/tech-docs/GTK-impl.html#GtkButton

There should be four actions for GailButton: Pressed, released, Clicked, 
activate, with an additional action toggle for GailToggleButton.

I had thought that we have decided that there would be one action for both 
GailButton and GailToggleButton, i.e. click the button. I cannot find any record 
of discussions on this topic.

If you think that the four actions should be implemented, please explain why.
