The plugin is ported to use Qt5 and KF5, including:
- Install rc file in additionally for WebEngine
- Fix up include files
- Use new Qt connect syntax
- Conditionalise Qt::SkipEmptyParts/QString::SkipEmptyParts ready for 5.15
- Use QUrl::topLevelDomain() in findTLD()
Note that a fix for D28647 needs to be incorporated into KIO, as otherwise the user agent can only be changed once.
