Found a couple of issues with the updater. First, bad logic on which formats to process, so that is fixed to handle modern, commander, and standard as of today - it will still need to be updated when new cards are released. Second, it was lookingfor KeyErrors when what is thrown from an array access is an IndexError. Finally, fixed the call to get the current datetime.
For Card Battle, added in support for Modern and Commander. Updated logic to get closer to using the Fromat object/table, although still need to come revision logic to have it use today's date to pick which formats are currently legal. Fixed navigation bar so that it shows you are in battle.
Removed py from the name of the website app.
Updated wesite app files to use a merged version of the skeletons from Django 1.7. No real changes here, but did it for completeness.
Fixed a deprecation issue with how class Meta is described in admin in Django 1.7
