Better support directory structure on Windows

[soc]

According to Windows conventions, the application dir should be inside of an organization dir.

e. g. instead of

{FOLDERID_LocalAppData}/_yourprojectname_/cache/

the cache dir should be

{FOLDERID_LocalAppData}/_yourorganizationname_/_yourprojectname_/cache/

This probably requires extending the factory functions or adding new functions.

This has been fixed in 4067d11.
