Network Calculations on server
Merge branch 'development' of https://github.com/CS3141-Fall2013/TSP-Project
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
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.

Finished remaining Kill Death features
