Support running on server/as Docker image

[zegerhoogeboom]

As mentioned in #4, mono fails with an error when starting on a server. I've come as far as determining it's caused by this line, which assumes a graphical interface (/browser) is present. More specifically, I'm trying to run this as a Docker container for which I currently have:

FROM debian:jessie-slim

ENV MONO_VERSION 5.2.0.215

RUN apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF

RUN echo "deb http://download.mono-project.com/repo/debian jessie/snapshots/$MONO_VERSION main" > /etc/apt/sources.list.d/mono-official.list \
  && apt-get update \
  && apt-get install -y mono-complete \
  && apt-get install -y wget \
  && rm -rf /var/lib/apt/lists/* /tmp/*

RUN wget https://github.com/ServiceStackApps/RedisReact/raw/master/dist/RedisReact-console.exe
RUN mkdir -p /app && mv RedisReact-console.exe /app
WORKDIR /app

EXPOSE 2337
RUN mono --version
RUN mono ./RedisReact-console.exe

The mono setup is simply copy pasted from the official mono image, except for replacing the mono version with mono-complete.

The error I'm getting is exactly the same as in #4. Perhaps there is a way to try { } catch () { } this line?
