Improve scores formatting

With Slacks "Message Builder", I made a PoC message

    {
        "text": "*Rankning*",
        "attachments": [
            {
                "title": "",
                "fields": [
                    {
                        "title": "Användare",
                        "value": "sandell\nerike",
                        "short": true
                    },
                    {
                        "title": "Poäng",
                        "value": "2 (4 lösta)\n1 (1 löst)",
                        "short": true
                    }
                    ]
            }
        ]
    }
