[Qt-qml] Setting default behaviour to QNetworkRequest::PreferCache

[shiva]

Hi All,

The default behaviour of qml when using Image { source: "http:// " ...} 
seems to be QNetworkRequest::PreferNetwork . I dont want thus behaviour, 
is there some way I can change this to QNetworkRequest::PreferCache, so 
that it applies to all qml http requests

Thanks,
Shiva
