Changing use of nickname to proper article title in various pages 
On various football related pages, the word "Socceroos" is used, occasionally as a link word to this article, but occasionally simply the word itself with no links. I have changed these examples to using the wikipedia title, Australia national association football team. We don't go around calling the St. George Illawarra Dragons the "Red V", the Penrith Panthers the "Chocolate Soldiers", nor do we refer to the GWS project as "AFL's Vietnam" or the "Canberra Giants". There is no need to use a nickname. Have put this here just in case anyone feels they need to complain about my edits.
