Show scheduled game number

[eduherminio]

Given that Schedule takes you to this ordered lists of games to be played, it would be good to be able to see in the viewer a reference of which game is being played.

Use case for this is knowing when your engine plays (i.e. games # 30, 44, 58, etc.) and with a quick glance at the viewer being able to estimate how long until their next one.

An option to do that without thinking too much about the UI is by adding the game number at the beginning of the [Server] message, so at least you can check the # of the previous game.
