Began refactoring
Finished refactoring for handling missing data. Set up framework for
logger. Changed teams from Team to String (the team's name), the
StatsParse class will take care of mapping team names to Team objects.
Fixed trailing whitespace bug
Added a HashMap for player names and their per-game stats.
Added offline use and logger. Bug: missing cs/gold values aren't logged
Finished implementing logging.
Added gen'd logs to gitignore.
