Support QJson 0.7 (still used in Precise)

Make it possible to change the server URL used by UrlBuilder.

Currently it initializes s_server once on startup - so subsequent calls to
Config::setMygpoBaseUrl have no effect.

This version lacks a QJson::Serializer::serialize(const QVariant&, bool*),
so emulate it by checking whether the returned QByteArray isNull.
