Add player stats to scoreboard in sauerbraten/cube2

We all like sauerbraten, but I wanted a persistent look at my stats as I played. As such, I have written the following patch to display relevant info. Thanks to #sauerbraten for help.

This works against stable, “Trooper Edition”. There is a patch for SVN floating around out there somewhere, which includes flags captured as SVN has that variable implemented and I didn’t feel like backporting it. Hopefully there will be a release soon and it will be moot.

So, just apply this from sauerbraten/, not sauerbraten/src.
