HW tournament statistics analyzer.

1. Added the new season (for the future) and 2 seasonal themes that were missed from the tournament filter. 2. Added the ability to view the list of unconfirmed reports for a specific player. For example, http://heroes3stat.appspot.com/unconfirmed/playername

The ends of the graphs look pessimistic at the end. Is this a bug?

No, the overall activity and the number of active players are unfortunately decreasing. I had a suspicion, and I confirmed it. Think about it yourself. I was advised to remove the current month from the graph, as it looks depressing. I will do it when I have some free time.
