fix message to 'winning' player when a Player in PvP logs out. It is now configurable via messages.yml.
Ender Dragon Damage now has two rules. Apparently the EnderDragin does damage with explosions, so there are now two entries much like the other explosion settings. I'm uncertain of what specific functionality would differ between them, but depending on the size of the explosion the non-block version might be desirable.
fix to prevent chests from being destroyed. Now any block with a blockState is protected from explosions. This is (hopefully) only a temporary fix until I can rewrite the logic involved (this means it will probably be around forever, hah)
