Decktricks: install 3rd-party programs in SteamOS without Desktop Mode

I spent a TON of time and had a lot of fun writing Decktricks, and I'm happy to say it's finally ready for beta. I would really love to hear how it works for you, especially if you're running on a non-Deck device (or using a non-SteamOS Linux on a handheld!). It's totally free and open-source, and will stay that way forever.

It's an installer/launcher for SteamOS 3rd-party utilities, like:

* Moonlight / Chiaki / GeForce NOW * Decky Loader * ProtonUp-QT / ProtonPlus * RetroDeck * Spotify / VacuumTube / Discord / Vesktop

It also makes it much easier to run (and add to Steam) system utilities, like:

* Nested Desktop Mode * KDE Connect * Software Center * Terminal * File Browser

The important bit is that it can do all of this, and more, from Game Mode! I use it all the time for myself, and honestly I don't even remember the last time I needed to boot into Desktop Mode for anything. I hope you all enjoy it as much as I've enjoyed writing it.

If you have any ideas or suggestions, feel free to leave me a comment or DM, or make an issue on the GitHub: [https://github.com/MrAwesome/decktricks](https://github.com/MrAwesome/decktricks)
