   about:config settings:
    - display_yahoo_totals - set this to false to hide the Yahoo totals.  
        I like my totals between my starters and my bench instead of under all players.  
        But, this script can't display all the totals for all the stats (e.g., OBP), 
        so you may want to keep the Yahoo totals displayed.

   Updates:
   04-Jun-2007 - Initial version
   04-Jun-2007 - Fixed bug where script was interfering with Yahoo script, and colspan was being incorrectly determined
   05-Jun-2007 - Fixed to only display totals on roster pages where it makes sense
   05-Jun-2007 - Fixed bug where totals weren't displayed in the correct column for opposing teams
   05-Jun-2007 - Fixed rounding error bug in ERA total calculation
   05-Jun-2007 - Fixed rounding error bug in SLG%; Fixed bug where totals row wouldn't display if no BN/DL players
   28-Jun-2007 - Added tooltip (title attribute) to display the number of earned runs allowed when hovering over the ERA value for a pitcher
   28-Jun-2007 - Added tooltip (title attribute) to display the number of hits/walks allowed when hovering over the WHIP value for a pitcher
   29-Jun-2007 - Added K/9 totals
   14-Jul-2007 - Fixed rounding error bug in WHIP calculation
   18-Jul-2007 - Add about:config option to hide Yahoo totals (display_yahoo_totals)
   24-Jul-2007 - Modify to show totals when Yahoo doesn't ('Week', etc.)
   06-Jun-2007 - Modify to not add totals line where it doesn't make sense
