This is a follow-up to T6799: Kleopatra configuration files in wrong places. One person testing the latest beta of Gpg4win 5 reported that some settings were lost (https://bugs.kde.org/show_bug.cgi?id=501447). It turned out that this was due to the new location of the configuration files.
To avoid unnecessary support calls we should migrate at least the most important configuration files, i.e. kleopatrarc and kleopatrastaterc.
