bug fix – auto-complete/menu in Category item in bulk edit of racers didn’t work
database management functionality added – database can be downloaded (download), uploaded (upload), add an explanatory description and possibly delete old and no longer used databases
addition of a menu of existing databases in the database file name editor in the basic settings, the database file name now does not contain the path but only the file name
when the device starts, it now checks if the database file is valid, if not a new databaseile is created
