Collect data on previous games

[brandonchinn178]

Since Sportradar doesn't have past data, find data on internet for previous games (wikipedia seems to be good, look at the schedule section) and make a JSON file of the form

[
    # for each game
    {
        'date': '1/1/2015',
        'winner': 'CAL' (see constants.py),
        'loser': 'USC',
        'winner_score': 10,
        'loser_score': 0,
    }
]

Then one of the collaborators will upload the data onto the Heroku server (and can be used for data on development servers)
