Make QStringList an alias to QList<QString>

Fix our API, so that QStringList and QList<QString> are the
same thing.

This required a bit of refactoring in QList and moving the
indexOf(), lastIndexOf() and contains() method into
QListSpecialMethods. In addition, we need to ensure that
the QStringList(const QString&) constructor is still available
for compatibility with Qt 5.

Once those two are done, all methods in QStringList can be moved
into QListSpecialMethods<QString>.
