Player Scoreboard

[mikyll]

A scoreboard showing the current score of all playing clients, activable with "TAB" command. There is already a score system which increments the player score when picking up a collectible, and a system that handles the scoreboard showing with TAB command.
Maybe this last one could be changed by updating the score on the server and handle the showing of the scoreboard on the client (without sending a command, which is quite useless).
