Juris Translator

(This is based on a previous pull request)
Translator fetches journal articles and cases (new) from Juris

Also,
```
item.shortTitle = item.court+", "+myDateString+" - "+item.docketNumber;
var caseName = ZU.xpathText(doc, "//*[.='Entscheidungsname:']/following-sibling::td");
if (caseName) {
  item.history = caseName;
  item.shortTitle += " - " + caseName;
}
```
looks clearer
