Starting Minimserver on system start

[simoncn]

The setup script uses init.d for autostart if this is available. If init.d is not available, setup uses systemd. On Ubuntu 17.10, init.d is available and the setup script uses it.

To install MinimServer in /opt so that it runs as the root user and starts automatically, do the following:

1) Unpack the .tar.gz file into /opt using sudo tar xf instead of tar xf
2) Run the command: sudo /opt/minimserver/bin/setup enable_autostart root
3) Don't attempt to enable desktop integration for MinimServer. Instead, any user who needs to configure MinimServer should use MinimWatch to do this.
