Launcher: Improve directory appending UX and heuristics (bug #7502)

- Recognize more asset directories and omwgame files
- Always let the user append the selected directory
- Automatically pick the user-selected directory if it's the only valid directory
- Add a caption to directory selection dialog, properly handle cancellation
