Save more information in meta data pgn file:
[TimeControl "240+6"]
[PlyCount "23"]

In the future:
[BlackElo "2000"]
[ECO "C60"]
[Opening "Spanish"]
[Variation "Cozio, 4.O-O g6"]

This is interesting to import the pgn file on other chess clients.

TimeControl - You could probably read the original time controls from the 
timemodel.
PlyCount - This doesn't really contain anything interesting, does it? But it 
would be easy to get the number from the gamemodel.
BlackElo - We can load more data about FICS opponents into the ICPlayer object. 
For the remaining player types, we don't currently have the data needed.
ECO, Opening and Variation - These are things you look up in a database. We 
could create a module to do it, either using a database we include, or by 
looking it up on the web. The opening name would be nice to include in the 
automated comments panel.

We should save clock time, elapsed move time and game analysis info (for engine 
players) too in comments  as they are described in extended .pgn spec.
