Add the Image and Library widgets from #196. In this iteration they replace the image `QLabel` in the existing widgets.
The `PaintWidget` in the `InstallingWidget` has been replaced by the future `LibraryWidget` that has progress indication.
The `ImageWidget` was also used to replace the image `QLabel` in `GameInfo` and `GameDlc` widgets.
