[banshee] Disable keybindings for IDisableKeybindings widgets

[Gabriel Burt <gburt src gnome org>]

commit d6f45d7788dcf6f6c9ee0470cdf4ca20d6360d15
Author: Gabriel Burt <gabriel burt gmail com>
Date:   Wed Mar 3 13:46:39 2010 -0800

    Disable keybindings for IDisableKeybindings widgets
    
    Previously Nereid would disable the single-char keybindings only if the
    Focus was in a Gtk.Entry; now it will also disable them if in any Widget
    that implements Banshee.Gui.IDisableKeybindings
