Updated Cover (drMerry)

Update by Armin Geller
news.cnet.com
further updated by Bonni Salles
My updates use the current rss feeds for CNet and eliminates extraneous areas and
sets the oldest_article to 1 as the feed generally has the present day and one day before.
You may want to set it to download daily for this reason.
