Autopackage support (binaries for Linux)

[thelusiv]

This is an excellent idea! I downloaded my first autopackage (for Inkscape 0.42 and was impressed by the simplicity. The only trouble right now is that the game does not support having data, executables and settings files in different places, so it will have to install to /opt/games/vdrift/ or /usr/local/games/vdrift/ as one directory, rather than spreading things out through the filesystem as is usually done with Linux appliations.
