Print messages to stdout even if the console is open

The idea behind not calling GameModel::Log in tpt.log is that that would not only print the message to stdout but also add it to GameView's list of log entries, which the console doesn't want. Sadly, this meant that messages also didn't make it to stdout when the console was open.
