Modify RSS Ticker to Pause Scroll during Mouseover

It is likely common for users to either modify a skin or install a particular skin that takes advantage of multiple RSS feed sets. In addition, users may modify their skin to allow multiple RSS feeds to run at various speeds.

At times, a user may wish to momentarily pause the RSS ticker to read a particularly long news headline. This modification allows the user to easily pause the RSS ticker simply by placing the mouse over the ticker itself. When the user wishes for the ticker to start scrolling again, they can simply move the mouse away from the ticker.
