Graph EdgeCollection edge add not working

[rosmo]

Looks like the API has been changed in ArangoDB, or something else is wrong. This should fix it:

+    this._gharial.post(data, function (err, body) {
       if (err) callback(err);
       else callback(null, body);
     });

There's probably other graph edge functions that are not working, but I haven't checked those.
