QQmlXmlHttpRequest - use readyread signal not downloadProgress

The readyRead signal (part of QIODevice base class) is the
appropriate signal for knowing when there is data available
in a QNetworkReply.
DownloadProgress is intended for UI elements e.g. progress bars.
Previously it was emitted at the same time, but now it is emitted
less often.
