Marshall Greenblatt 558a8a3658 Implement improvements for request handling (issue #1327).
- Add a new CefRequestHandler::OnResourceResponse() method for inspecting the request/response headers and potentially restarting or redirecting the request.
- Add a new CefRequest::GetIdentifier() method for tracking a request across multiple CefRequestHandler callbacks.
- Pass a CefRequest object instead of just the old URL to CefRequestHandler::OnResourceRedirect().
