If we do not change anything, Okular config files will stay in several different locations (same issue we had with Kleopatra):
%LOCALAPPDATA% (okularrc), %APPDATA%/okular (okularstaterc) and %LOCALAPPDATA%/okular/docdata
Currently, in Gpg4win 5 (and in VSD 3.4 if T7700 is done) all Qt-programs are configured via qt.conf to use %GNUPGHOME%/kleopatra (if GNUPGHOME is set).
Which is fine when we only have Kleopatra. But where do we want to store those application related files for Okular?
Suggestions to use for both Kleopatra and Okular:
* %GNUPGHOME%/kleopatra (i.e. leave as-is)
* %GNUPGHOME%/kde (i.e. use a more generic name; kleopatragroupsrc would stay in %GNUPGHOME%/kleopatra)
Note: A location that depends on the application name (e.g. %GNUPGHOME%/$applicationname) might seem nicer, but it would require extending our patch for QStandardPaths. Moreover, it will cause problems if config files need to be shared (which, at the moment, doesn't seem necessary).
