Changed IDs to strings and the service accessor to call api/v2/
Fixed app data containing a long, but trying to pull out a string - now if a
user has previously used the app, the first time loading it will simply load
the default on IDs (team, season, and last watched clip).
A few calls had slightly tweaked json - this commit should fix problems with
reading that new json.
Cleaned up a spot where a string was being unnecessarily cast (to a string).
