Move weeks listing into display_seasons_weeks()
Make future week check more pythonic

While writing this simple patch, I wasted an hour debugging a problem where
datetime would throw an error /only/ after the addon had been run once...

http://forum.xbmc.org/showthread.php?tid=112916

I don't know what the real problem is, but I think it's a Python bug.
Bumping xbmc.python to 2.14 (for Gotham) did not help. :-/
Small cleanup

Remove duplicate reset (done in self.init)
Separate season and non-seasonal shows

This way Super Bowl archives (and any other future non-seasonal shows)
will display under all seasons.

Also, shows are now alphabetically sorted.
0.5.1 development release (Tom Landry Edition)
Pass arguments to WindowXMLDialog

This is almost certainly a bug (though apparently a common one among xbmc
addons). Confluence passes the args explicitly, and I figure what the
 default skin does is a good idea.
Convert game_common to a class (pigskin)

This accomplishes two things. 1) turns everything into a class, making
it easier to track information such as subscription, etc. Future work
will use this more. 2) Finally remove the last XBMC bits from
game_common.

This module can now be used completely independently of XBMC, and can be
used interactively in iPython, which will help debugging efforts
immeasurably.

Closes Issue #35
Bug fix: raise on gamepass login failure
Don't open skin after Login Failure or blackout
Rename game_common module to pigskin
Use object's subscription data
re-unify login functions
Some variables cleanup
Fix fallout from class conversion

These slipped through before I renamed the file, and it's a bit annoying
to squash these back through the rename. So here they live, in all their
unimportant, unintended glory.
Small cleanup of service_blackout
Use a descriptive variable name for the http_session
Remove potentially problematic trailing .'s in log messages
Move variables so they are private to each object

Otherwise these would be shared among all instances of the object
Move RedZone on-air check to pigskin
