BodyHealth - Locational Health & Damage

Added a world blacklist that can be turned into a whitelist to disable- or only enable body health in specific worlds.
Added a WorldGuard hook: BodyHealth can now hook into WorldGuard and register a flag called 'bodyhealth' to enable/disable body health in specific regions. Added bypass permissions to control damage and regeneration per player and body part
Fixed the KILL_PLAYER effect, to (hopefully) no longer cause double deaths
