Modified by Gered King (flingmaster5000@hotmail.com) - February 2005
  - cleaned up code
  - prefixed functions with "news_"
  - added news_setWidth(), news_setHeight(), news_addContent()
  - news_populate() now requires a DIV id passed which will be the scrolling target
  - Modified to use a scrollbar
  - added news_stopScroll() and news_resumeScroll()
