Add refactoring option that creates a getter, setter and change signal from a member

I often find myself creating properties in C++ that will be exposed to QML. Having a refactoring option that adds the signal for me and writes the setter would save me quite a bit of time after a while:

void Foo::setBar(int bar)
{
    if (bar == mBar)
        return;

    mBar = bar;
    emit barChanged();
}
