should this be WebURL?

https://code.google.com/p/chromium/codesearch#chromium/src/net/url_request/ur...
https://code.google.com/p/chromium/codesearch#chromium/src/third_party/WebKit...

In Chromium, net::URLRequest::referrer() is std::string.
And in blink, WebCore::Referrer::referrer is AtomicString.

So I want to use WebString here.
