Add template for Astroneer using AstroTuxLauncher

[JoeJoeTV]

This template is used for running an Astroneer Server on Linux via AstroTuxLauncher and WINE.

Currently only supports Linux, as AstroTuxLauncher only supports Linux, but that may change in the future.

I created this template some time ago to work with AstroTuxlauncher, which I created to make hosting the Astroneer Server easier and it has been working fine for hosting a server so far.
