Added 2014 Schedule

Added the 2014 Giants schedule (from
sanfrancisco.giants.mlb.com/schedule/sortable.jsp?c_id=sf&year=2014)
and pointed the data source to this new JSON file.
Reformat date in JSON schedule

I realized that I did not pay attention to the year format and
hopefully fixed it to avoid any JS issues as mentioned in
Pull Request #12
Merge pull request #16 from jasonferrier/master

Update for 2014! Thanks Jason.
