Call the DidStartLoading/DidStopLoading methods on the WebViewDelegate interface whenever we receive the initial response for a byte range request and when the request eventually completes.

This ensures that the throbber continues to spin when these requests take a while. 

It stops spinning during load when the document load is cancelled by the plugin process. This occurs when the plugin invokes NPN_RequestRead the first time on the stream.
