Add support for Linux

[PoorPocketsMcNewHold]

I suppose the title is self-explanatory. Shipping it under a AppImage, a snap or a flatpak should clear any issues for incompatibilities between distros. Outside of that, I suppose making a .deb, .rpm and dedicated AUR should do the job well.

Definitely doable, but a huge undertaking. I personally don't use Linux for gaming so can't be much help here. Pull requests welcome 😄

Perhaps to limit the scope (avoiding a rewrite as to how you detect games etc.), could be a Linux version of this tool that only features configuring the grid view images etc, be feasible?

I haven't looked at the code yet, but I'd be happy to at least look into it.

There are two pull requests that add support for Linux, but I haven't been able to test them soon. This support will eventually come.

With the release of the Steam Deck, it'd be great if there was a flatpak port in flathub. Since the deck officially supports installing software from there out of the box (other software installed via package manager or so in the system partition would be wiped out after each Steam OS update).
