Add option to prevent querying the individual servers

[Geesu]

I just want to understand the set of ip/ports for a certain game, I don't need to wait to query the individual server. So this introduces a -noinfo parameter which will just return the ip. Example:

	{
		"ip": "5.44.44.20:27077",
		"protocol": 0,
		"name": "",
		"map": "",
		"folder": "",
		"game": "",
		"players": 0,
		"max_players": 0,
		"bots": 0,
		"type": "",
		"os": "",
		"visibility": "",
		"vac": false,
		"rules": null
	},
