[Gtk-sharp-list] Issue concerning button image

If I need only an image without the text and I don't need all of the 
features in the Gtk.Button I will normally just use a Gtk.Image in a 
Gtk.Event container widget, of course that doesn't have all the benefits 
a Gtk.Button does but I makes for a quick simple solution to the button 
border problem.

I hope that helps.
