Updated Yoggrt ad code per changes from BuySellAds.

New JavaScript code to place ad on page. Removed all references to old script

Completed rework for Yoggrt add code change.

Apparently I missed removing one part of the old code and therefore got another
email about updating my site. Hopefully it is all correct now.
