Game.java spends way too much time/memory building the gamePlayback string

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run a game with lots of fleets using PlayGame.jar
2. It is really slow
3. Because if you keep doing string += "some stuff"; in Java, it has to make a 
new copy of the _entire string_.

Attached is a patch which uses StringBuilder to build the gamePlayback string.  
This engine is much, much, much faster.  Warning: the output appears to be 
correct with a cursory investigation, but I'm not totally sure I haven't broken 
it.
