feature: UI: LDN Games Viewer

This window can be accessed via "Help" menu in the title bar.
This menu's data is synced with the in-app-list LDN game data, and that has been modified to hide unjoinable games (in-progress and/or private (needing a passphrase)). You can still see these games in the list.
