Feature: choose player from player list to hide the game board from.

[joshzcold]

For fast money we have to pick two team mates from 1 team.
We have to tell 1 player to "leave the room" or video call while we run the 1st fast money round.

While they leave the room the game board is still visible on their joined device.
Most people in spirit would choose not to look, however the game should up hold the rules of the game.

It would be nice if the admin had a choice on who to "hide" the game board from during fast money.
