choke downloadProgress signals
The QNetworkReply::downloadProgress signal is intended for updating
user interface components (e.g. a progress bar).
Limit signal emissions to 10 times per second, with an additional
signal just before the finished() signal to provide the 100% progress.
For the size of download where a progress bar is necessary, this
update frequency seems sufficient.
The implementation is done by dropping signals which would be emitted
less than 100ms after the previous signal emission.
