    GTK PrintToFile settings
    
    To make setting output directory and filename simpler in the PrintToFile
    dialog two gtkprintsettings have been added GTK_PRINT_SETTINGS_OUTPUT_DIR
     and GTK_PRINT_SETTINGS_OUTPUT_BASENAME.
    
    This will reduce the code needed to implement a better name than "output.pdf"
    and actually makes more sense than the existing setting
    GTK_PRINT_SETTINGS_OUTPUT_URI which doesn't work seamlessly with
    GTK_PRINT_SETTINGS_OUTPUT_FILE_FORMAT like the new settings do.
