fix two bugs in the custom script class example

1) fromScriptValue() needs to call qvariant_cast() on the data, in
order to be symmetric with toScriptValue().
2) use the overload of newFunction() that takes a prototype object,
so that the prototype.constructor and constructor.prototype
relationship is set up correctly; otherwise the instanceof operator
won't work.
