Adding new Seasonal ladder Valentine Venture 

Adding the format for the new Seasonal ladder, 
Valentine Venture, and also commenting out Wonder Winterland.
Added the random team selection for the new Seasonal ladder for 
February Valentine Venture (randomSeasonalVVTeam).
It's a doubles ladder that chooses three couples for each player.
This one uses level balance with a little tweak to tone down
Kyurems and help Magikarp.
