    batch-rename-dialog: disable metadata for illegal metadata chars
    
    If the metadata has the character "/" the metadata cannot be used.
    
    Rather than showing a conflict when this metadata is used, it should
    actually be disabled, because the user will never be able to rename the
    files using this metadata.
