Wine Support

[nea89o]

I would love for this to allow selecting the game location manually for non standard installation locations. More specifically I am requesting this because on Linux (using wine) the steam games are in the Z drive in a non standard (not a ProgramData folder) location, which makes it impossible (without linking directories) to use this software. See also https://github.com/pointfeev/CreamInstaller/issues/101. I am not sure if this would fix all Linux issues and work with all games, but this seems like a somewhat easy-ish to implement solution, and like something that might be useful for linux gamers as well.
