New flatpak runner is out: 0.4.0

This time it has been mainly about making it usable. From now on, you don't need to make GL extension manually anymore - its made for you on the first start of flatpak-runner.

The app takes care of refreshing the list of flatpak applications installed on your device and generates corresponding .desktop files. As a result, you can launch them as if they are SFOS apps from the app grid.

When started without hosting any app, it will show the list of installed flatpak apps and will allow you to tune environment for each of them. You can add default and app-specific env variables, change QT scaling and DPI parameters. For qtwebengine based browser, I recommend to set scaling to 2 or 3 (depending on your device) for better hidpi screen support.
