Auto export

[ksz16]

There is an automatic backup option that exports the entire database to a .db file. Could you also add an option to automatically export to a .csv file?

And second question: could you consider changing the name of the file used during export? Currently it uses the schema "openScale user.csv". It would be more convenient if the name included a timestamp, e.g. "openScale_user_%Y%m%d.csv"
