Award2

I didn't want to have to do this, but the original Award model was too inflexible to handle old (pre-2007) awards. Also, the old model didn't deal with multiple recipients of the same award (ex: Regional Winner, Dean's List) consistently.

This pull request only adds the Award2 model, updates the parser and manipulators accordingly, and changes the parser tests to use the new format. A later pull request will change the frontend and admin pages to use the new model.
