Ending games

[Dread]

I would like to have a concede option so its possible to end the game either if your opponent stop playing or what ever other reason.

[Logitude]

My thinking has been that matches where the current player hasn't changed in about a week will get archived. There will be a separate archive page that could be used to revive matches.

I could add an explicit abandon option, but I have no way to skip anyone's turn or substitute a bot, so the match would end.
