Checkium

Seems that it works fine on singleplayer

@Draco18sThat was a test, even after frame declaration it doesn't work.

@tazdevil971There's a missing "server.cfg" also in NEI

@tazdevil971That could also be a problem, and after that one got fixed the new one started crashing, could we send us the new crash?

I'm trying to make a JFrame that will log all players kills, but the LivingDeathEvent is not firing.
