Integrate arma-manager module

[Saborknight]

Dahlgren implemented functionality that allowed easy starting of an arma 3 server (https://github.com/Dahlgren/node-arma-server). He doesn't necessarily allows stopping it, but it is supposed to return the PID of the executable! We can use that to stop and check if the process is running.
Otherwise, checking the port listener and then grabbing the PID related there is another option.

Controls to implement:

• start
• stop
• status
• restart - Is there a way we can send chat commands to the server? Then we could imitate #restart
• update - Updates the game and any mods that are out of date. Use the FASTER XML to check on if anything is out of date? Might not work since FASTER is not guaranteed to be open or have checked for out-of-date mods in a while
• attendance - List the players who attended for the last event. An event is described as any session where the players were connected at any point during the 1900-2100 time period on a Wednesday, Thursday or Sunday
• add_mod - Adds a mod to the start parameters of a particular server
• remove_mod - Removes a mod from the start parameters of a particular server
• add_server_mod
• remove_server_mod

Found a game queryer to solve all our problems: https://www.npmjs.com/package/gamedig
This includes not just Arma 3, but also Space Engineers, Teamspeak, Garry's mod, Minecraft, and more, see the games list here: https://www.npmjs.com/package/gamedig#games-list

So, this game query-er doesn't do anything except return information on the game server instance. I should have guessed from the name... Good for the status command, but that's pretty much it.
Back to Dahlgren!

Updated the feature list of commands

For the servers to run independently of this driver, I need to add a pull request to add

{
    detached: true,
    stdio: 'ignore'
}

to https://github.com/Dahlgren/node-arma-server/blob/e1f1e75888491c4fcb330f25b61818ae7397609f/src/server.js#L112 and https://github.com/Dahlgren/node-arma-server/blob/e1f1e75888491c4fcb330f25b61818ae7397609f/src/headless.js#L71

Created our fork of arma-server for this: https://github.com/2bnb/node-arma-server

I'm now changing the implementation from Dahlgren's ArmaManager to use the commandlines that FASTER outputs for use with it's profiles and mods.
