Edited Issue: Exception when creating Dates in V8ScriptEngine [113]

Hello,

I'm trying to create/parse date from a JS evaluate and return them as strings back into c# code as such:

```
using (var engine = new V8ScriptEngine())
{
resultEval = engine.Evaluate(expression);
}
```

where my `expression` is

`new Date()`

and it return an "Microsoft.ClearScript.V8.V8ScriptItem" object with an "UnderlyingSystemType" saying:

'((Microsoft.ClearScript.ScriptItem)resultEval).UnderlyingSystemType' threw an exception of type 'System.NotImplementedException'

Now, I feel like this *should* work, but it's not. Any ideas? I don't think anything went wrong during the build/reference process. Other JS libraries such as Math work flawlessly.

Also, this is only an issue when trying to create a `new` date. Calling `Date()` works, but it only displays today's date.
