QStringList: add op= overloads 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.
