suggestion: FDD: grant points based on most damage dealt & by dealing the last blow to 0HP

[CreeX0rZ]

Two ideas in attempt to prevent kill stealing, this might also be a better way to award kills / Event points:

1. Grant a kill/point to a person who did the most damage to the enemy,
2. Grant a kill/point to a person who dealt the last blow & dropped the enemy to 0HP

Note: Might also apply to different arenas, dunno
