meadow: alliances with more than 2 players

[GoogleCodeExporter]

I think before adding a third player to an alliance, I'd want to 
institute a rule to keep it fair.  What about something like this: 

1) Two players may always ally to form a new team, no matter how 
dominant that new team would be. 

2) A player may not join an existing team (of at least two players) if 
by joining that team they would more than double the score of the next 
largest team. 

This would encourage underdogs to band together to defeat the top 
team, and discourage the top team from snowballing to victory with a 
bunch of hangers on. 

I think I could implement this change in a fairly straightforward 
manner. 

Regarding player ranking.  I like Templar's suggestion of keeping 
total wins, %wins, and total victory points as three separate scores 
and simply report on all of them and let the player community decide 
which one they care about the most. 

If we ever get enough players, I will implement a ranking system that 
takes into account the ranking of the players you defeated.  But We'd need to 
have a lot more players before it would be worth implementing that.
