Fix for football live blog key events/scores overlap 

Fix for key events overlap on football live blogs that haven't got the football/football tag. 
Now changed so that key events aren't fixed on live blogs in the football section.

Example of problem: http://www.theguardian.com/football/live/2014/oct/11/brazil-argentina-live-friendly-beijing
