[Feature] Change Characters Between Wi-Fi Races [Author] MrBean35000vr [Information] 
When in online play, the player's character, vehicle and drift mode choice may be changed between races by pressing + on the Wii Remote (or Start on the GCN Controller) when on the VR screen. This simply takes the player back to the character select menu, and then returns them to the vote when they have reselected. If the time limit expires, the currently selected options are taken.
