Klaus Basan c282d4e1f8 Ref T295, network watchdog optimizations 
* constructor can pass network accessibility as default
* ping URL now constructed in global setup
* watchdog will prevent unnecessary signals by checking if state has really changed (there are redundant QAM signals for QNetworkAccessManager::networkAccessibleChanged)
* refactorings, thread checks
