Wreckfest failing to start on headless server about gameservers-docker

[raynfalldown]

@scottmando2000 I had the same issue as you and was able to fix it yesterday by adding "xvfb-run" to the start-wreckfest.sh script and a DISPLAY environment variable to the Dockerfile. I have to create a full PR still since I modified a few other things, but this is what my final command is:

Line 114 of start-wreckfest.sh xvfb-run exec wine Wreckfest.exe -s server_config=server_config.cfg
Line 4 of Dockerfile ENV DISPLAY :99

I hope that helps. I also ran into some .wine issues where I had to clear the /home/steam/.wine folder and re-run winecfg as the steam user. You may run into those as well, but hopefully not.

Just added PR #31 with the changes I have made.
