[LyX/master] Consider file encoding for modules in reconfigure

    Consider file encoding for modules in reconfigure
    
    If the modules are not in utf8 then we warn and skip that file
    like it happens for layout files.
    
    It would be nice in both cases to have a warn in the gui and not only in the config.log
