Request: Add Flathub as Source

[lesnake 0]

Flathub provides some games like https://flathub.org/apps/details/org.supertuxproject.SuperTux.  It would be great if I could add flathub as an source for SuperTux and other games avaiable there. The fields required should be the flathup id (in case of supertux: org.supertuxproject.SuperTux)

 

If it gets added a field for the flatpak save path might be useful as well  (though it should also be the same folder as normal, but XDG_CONFIG being .var/app/<id>/config and XDG_DATA being .var/app/<id>/data).

Some games might behave differenly, so we should be able to set the config and data path.

I just realized this probably belongs in Articles and troubleshooting, sorry for mixing things up
