Importing with option isotag1=3000 for non-marc iso files resulted in invisible additional fields in the database. This commit is solves this for non-marc databases. For marc databases the export is enhanced but the import needs additional work. In all files several fixed strings are replaced by translatable strings. Detailed modifications: - exporta_txt.php: always preselect mx+improved strings - exporta_txt_ex.php:Improved command for marc database and non-marc database - clean_db.php: removed option isotag1=3000 - inc_check_line-end,php: no error if file has 1 line without line-end. This is produced by export for marc. - vmx_import.php: removed option isotag1=3000
