Add more information about lobby matches

[Stan]

As of now only few informations are displayed in the lobby about the games, it would be nice to add more details:

• Players and Teams
• Connected players and observers (related #3143)
• Gamestart-timestamp
• Gametime (#3023)
• Time of player defeat
• Number of allowed observers

Sample Image from elexis to demonstrate

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.
