Alert and page for overdue judgements

I've added a "due_for_judgement" page so that users can view all of their predictions which have passed the deadline but still have not been judged. Users can go to http://predictionbook.com/users/username/due_for_judgement to view them. If there are any predictions due for judgement, an alert message is displayed on every page with a link to the url above.

I also changed to copyright notice at the bottom from "2008-2011" to "2008-2013."

This is my first time using Rails so let me know if I've done anything in a non-railsy way.
