示例1: setPrototype
/*!
If this QScriptValue is an object, sets the internal prototype
(\c{__proto__} property) of this object to be \a prototype;
otherwise does nothing.
The internal prototype should not be confused with the public
property with name "prototype"; the public prototype is usually
only set on functions that act as constructors.
