[gtk+/places-sidebar: 34/53] New signal show-error-message

[Federico Mena Quintero <federico src gnome org>]

commit 4759365590278572f38436a80a61e81f0dcad312
Author: Federico Mena Quintero <federico gnome org>
Date:   Tue Oct 4 16:47:31 2011 -0500

    New signal show-error-message
    
    We need to ask the caller to pop up error messages for us, so it can do
    it with its own conventions:  pick the right transient window, use a status
    bar rather than a dialog, etc.
