    [Hyena.Gui] Fix ActionManager toolitem icon sizing
    
    Before, any custom widgets populated into a toolbar would not inherit
    the size of the toolbar.  For example, in Banshee the Next button (a
    MenuButton) would remain at size = LargeToolbar even if the toolbar size
    had been set to Menu.  Fixes bgo#609265
