Changed Factiva translator, based on the webpage

* there seems to be no XML-export from Factiva and before the translator was based on this XML-export
* now the translator identifies the information directly on the webpage(s)
* Handles Frame Option well as No-Frame Option (with monitorDOMChanges)
* handles different display options
* add stable url, snapshot
* add normalization of date
