    NotificationDaemon: add rewriteRules infrastructure, use it for xchat
    
    Changes notifications like:
    
        XChat: Private message from: danw (GimpNet) blah...
    
    to
    
        danw: blah blah blah blah
    
    (the "XChat" being unnecessary since there's already an xchat icon
    there anyway.)
