Add more information about lobby matches

[Stan]

As of alpha 19 only few information is displayed in the lobby about running games. It would be nice to add more details:

• Connected players and observers
  • We already show the list of initial clients. But it is not updated with late-observer-joins, resulting in only some observers being listed for that game.
  • Sometimes people are listed in multiple games if they were present when it started. So making that distinction between online and offline would help clarifying.
  • Online players could appear in their lobby color while offline players could be displayed in gray.
• Gamestart-time
  • Useful for estimating if the game will end in the near future or if it has been started just seconds ago. (see #3023)
• Teams
  • Would be nice to see and wouldn't add too much information to the gamelist-packet and GUI. See the outdated screenshot.
• Defeated players (maybe)
  • Would also help estimating if the game will end soon, also if it is worth to join as spectator.
  • Using a strike-through font would be nice for that (we don't have one currently).

Notice that we might reuse code in source:/ps/trunk/binaries/data/mods/public/gui/replaymenu/replay_menu.js​ that constructs the team/civ/ai string.

Notice the "lag estimation" would have to take paused times into account and should not be added until after #1950 is solved.

The turn number doesn't seen to be displayed, but it is used to compute the ingame time.
