Re-order Doubles formats
Re-order the Doubles formats so they are ordered in the same
fashion as the Singles metagames.
First of all, Random Battle, which will be available soon.
Then, the Smogon officially endorsed Doubles metagame.
Then, Nintendos Doubles metagame VGC '13.
Then, Custom Game and last but not least Challenge Cup.
Add Smogon Doubles Ubers challenge option
