Improve settings migration and management (#5107)

* Settings can now be optionally removed during uninstall (didn't find how to translate)

* Settings import from previous versions now optional

* Hopefully cleaner implementation

* This crashes (already on 2.2)

* Translation

* Remove broken settings import from companion9x

* Fixes for MainWindow
