Added kd tuple for tracking kd statistics
Scoreboard is done, the following tasks are left to do:
1. When players quit, need to remove them from the scoreboard
2. Scoreboard needs to be sorted in order of kills
Merge pull request #36 from aweidner/master

Finished remaining Kill Death features
Scoreboard is now sorted in order of most kills.
Players are now removed from the scoreboards if they exit the server,
but as a side effect, players also now loose thier kill/death stats
when they die because of how death is implemented in the game.  Either
this is a feature (only killstreaks matter then) or we need to
re-implement dying.
