Linux test

This is only a test. I am not yet promising a Linux build for this game. Especially not since my current tests were not really great. Let's put it this way, the game loads, or rather, the launcher loads. You can see the intro scroll (I could not test if the sound works, though), but there it appears to end. The launcher does not appear to take any input from the user at all. In the game itself works, I cannot yet tell.

If you know the solution to fix this, let me know.
