Linux native version #438

As more and more gamers are migrating to Linux. Specially SteamOS and Bazzite (my self included). Would be really useful and awesome to have a real native version of this excellent tool for XCOM2.

Besides there are two version of the game playable in Linux: Windows and native Linux versions. So adding compatibility for both could be a real bonus for all those of us who own the game.

I know the actual Windows version works just well enough with proton, but lacks a lot of functionality (too small font size, no possibility for grouping, sorting, and others), and, as stated, no native Linux version support.

Could settle for a revised-updated Windows version that has more compatibility with proton, so all original functionality is restored.

Thanks in advance for your work.
