        Introduce QScriptOriginalGlobalObject.

        QtScript exposes more functionality than JSC C API. Sometimes it is

        necessary to take a shortcut in implementation. Really often we have

        to use a standard JS function. These function could be changed or

        even deleted by a script, so a backup of a reference to an object is needed.

        In them same time this is rather a workaround then real fix, so the code

        should be separated and changed easily in future. It is why we need

        the new internal class.

        The patch fixes a few crashes.

        [Qt] QScriptEngine should work correctly even after global object changes

        Implementation of QScriptValue::isArray()

        Since we don't have access to the [[Class]] internal property of

        builtins (including Array), the solution was to keep the original 'Array'

        (constructor) and 'Array.prototype' objects and use them to identify

        if a given object is an Array.

        Also uncomment some tests and add some tests of newArray() that

        depended on isArray().

        The patch contains implementation of the QScriptValue::property() and

        the QScriptValue::setProperty(). It is not full functionality, as these

        method are too complex for one patch, but it is enough to cover about

        95% of use cases.

        Missing functionality:

         - Few of the PropertyFlags are ignored.

         - Only a public part of the ResolveFlags can be used (ResolveLocal,

         ResolvePrototype).

        A lot of new test cases were added.
