[gedit/wip/loader-saver: 16/48] GeditDocument: remove error param of the "loaded" and "saved" signals

[Sébastien Wilmet <swilmet src gnome org>]

    GeditDocument: remove error param of the "loaded" and "saved" signals
    
    Plugins don't need the error paramater, the signals are useful only on
    success.
    
    The signal marshallers are set to NULL to use the generic marshaller.
