Commented Unassigned: interface merge with JS classes [897]

The current release does not seem to handle the following properly, even though it is handled fine by the online Playground:

```
interface String {
newMethod ():string;
}

String.prototype.newMethod = function ():string {
// ...
return "something";
}
```

and I can't seem to add newMethod to an interface for String in VS2013 anywhere.

Thanks

Todd
