v4: Enable primitive conversation to QQmlScriptString in javascript
This makes following QML-code proper working:
ParentChange {
x: 0
Component.onCompleted: x = 10
}
where x is a QQmlScriptString.
Before this patch an error-message would be thrown that the
bool/int/string/etc cannot be converted to a QQmlScriptString.
With the patch primitive types including null and undefined are
proper converted to a QQmlScriptString. The patch ignores (as
in not implements) function/binding assignment.
Unfortunately since commit
aa25ad8d5f4 its not possible any
longer to instanciate QQmlScriptString what means there is
otherwise no (easy) way to inject a QQmlScriptString from
within Javascript.
