Points system

[64bitpandas]

Every player should have a field keeping track of who did how many damage to the player. When the player dies, the game should award 2 points to the player who did the most damage, and 1 for all assists. The game should then push out a global notification saying who died and who killed them.

Score is displayed on the HUD - both team score (in the middle) and individual score (off to the side).

Team scores implemented as of commit ce42cbf, but individual scores still need work.

No longer required as a core mechanic. Will be put to low priority.
