QStringList: add op<< overload for QList<QString>
QStringList << QList<QString> already compiled, but was interpreted as
QStringList << QStringList(QList<QString>), which involves the QList
copy ctor. Adding the overload saves that copy.
Cannot use a using declaration here, since the return type is different.
