Studentenwerk dish_type not working for dish types with several lines

[lukasdenk]

When the Studentenwerk food page lists a dish type with several dishes, like here:

...only the type for the first dish is detected correctly. The other types are not recognized. See JSON snippet from here:

                {
                    "name": "Arabischer Couscous mit Karotten und Kichererbsen",
                    <...>
                    "dish_type": "Studitopf"
                },
                {
                    "name": "Tagessuppe",
                    <...>
                    "dish_type": ""
                }

I have already fixed this issue, just wanted to create an issue for documentation purposes.
