Subject: [PATCH] Euchre::Dealer: Add start_game, with new in_progress state

This does two things:

  1. Add the scaffolding for a start_game action
  2. Add the in_progress state to the game

(2) is only really used for preventing join_game; there is functionally
no equivalent to why this is superior over the checking for 4 players,
except for it is slightly more readable and is a nice field to have for
debug.html / the eventual listing of games (?)
