v0.2 -- Now supporting baseball

Sports Stats can now properly display MLB and NBA standings,
scoreboards, and schedules.

I reworked the display of game results and schedules to use multiple
screens with pause prompts.

I am still using xmlstats as my data provider while I work out the
front end. At some point I may switch to a different service, or write
my own scrapers.

To come:
* Support for user preferences and favorite teams
* General interface cleanup (return to main menu instead of exiting
program, etc)
