0006529: Cancelling database upgrade can corrupt the database. Ensure database is unlocked when cancelling upgrade. Make links in dialogues into clickable hyper-links. Ensure dialogue windows stays on top. Reword warning and error messages to use Bsddb version, schema version and Family Tree consistently, to be clearer about the choice the user is being offered, and to provide hyper-links to more information.
