Change C++ parameter type used for var parameters in QML declared signals "signal someSignal(var foo)" mapped to foo being of type QVariant. Unfortunately that is a "lossy" type and it cannot represent all JavaScript values, including for example function closures (as reported in the JIRA bug). Instead we should use QJSValue. It is an important behavioural change because it affects the presumably rare case of somebody declaring a signal in QML with such a parameter and connect to it from C++ (or trying to emit it) - in that situation the code needs to be changed.

- Signals declared in QML that take "var" parameters, are now using QJSValue
as C++ type for these parameters, instead of QVariant.

- Introduced QQuickWidget. This is the equivalent of QQuickView in the
QWidget world. It allows easy and flexible embedding of QtQuick
scenes into widget-based application windows without the
restrictions imposed by QWidget::createWindowContainer().
