/* 
	Used to asynchronously run an HTTP request.
	Displays a simple animation on the UI to show the application hasn't frozen.  Can be canceled by the user pressing B.

	Usage example:
		std::shared_ptr<HttpReq> httpreq = std::make_shared<HttpReq>("cdn.garcya.us", "/wp-content/uploads/2010/04/TD250.jpg");
		AsyncReqComponent* req = new AsyncReqComponent(mWindow, httpreq,
			[] (std::shared_ptr<HttpReq> r)
		{
			LOG(LogInfo) << "Request completed";
			LOG(LogInfo) << "   error, if any: " << r->getErrorMsg();
		}, [] ()
		{
			LOG(LogInfo) << "Request canceled";
		});

		mWindow->pushGui(req);
		//we can forget about req, since it will always delete itself
