Display player names in /status

[greatman]

Would be nice to have the players name shown in the /status json that way we could shown player heads (maybe not in the current status page but custom stuff based on this).

Something like this:

{
    "dead": {},
    "alive": {
        "Bungee": {
            "bungee": "2/300",
            "players": [
                "greatman",
                "vemacs"
            ]
        },
        "Servers": {
            "fallout": "0/32"
        }
    }
}

mcstatus.py does provide a player sample field, might be worth making the data available
