PySide does not make setters for fields that are a variable pointer to a constant value

The method CppGenerator::generateClass in generator/shiboken/cppgenerator.cpp has the following code:

foreach (const AbstractMetaField* metaField, metaClass->fields()) {
    if (metaField->isStatic())
        continue;
    writeGetterFunction(s, metaField);
    if (!metaField->type()->isConstant())
        writeSetterFunction(s, metaField);
    s << endl;
}

Because the setter is only generated if the field's type is not constant, fields declared as const SomeType* will not have setters generated. This is the case for QStyleOptionViewItemV3::widget, and thus further complicates PYSIDE-115, making it impossible to create a proper instance of QStyleOptionViewItemV4.
