'clicked' and 'middle-clicked' signals prevent normal activation behaviour in gtk.Menu.popup()

[Denham2010]

When using AwnIcon's 'clicked' and 'middle-clicked' events to open a gtk.Menu.popup(), items in the popup menu can only be activated by the same button that launched the gtk.Menu.popup().

Replacing 'clicked' and 'middle-clicked' with 'button-press-event' restores normal gtk behaviour, ie. gtk.Menu.popup() item activation can occur with any button.

AwnIcon's "clicked" and "middle-clicked" signals are emitted on mouse button release, therefore as Gtk+ docs say:

The button parameter should be the mouse button pressed to initiate the menu popup. If the menu popup was initiated by something other than a mouse button press, such as a mouse button release or a keypress, button should be 0.

You should set the button parameter to 0 when displaying a menu in the signal handlers.

For clarity this was from documentation for gtk_menu_popup().
