    [report-core] handle export properly
    
    export code was tested using a custom saved-report, needing to call
    the parent template export code. this could not work when a parent
    template export code was called. enable path to call parent or custom
    export-code.

    [taxtxf.scm] compact, allow error to console
    
    taxtxf error handling is designed for gui. add code to call
    gnc:gui-error which can also dump error to console if gui is not available.
