BodyHealth - Locational Health & Damage

A few things...

• Added SOUND effect to play sounds to only the target player
• Added an option to disable BetterHud's entity popup feature
• Added customizable offsets to BodyHealth's HUD (can be found in a new "position" category at display.betterhud)
• Added yet another safety feature for attribute modifiers to ensure they are removed correctly in any case
• Updated the effect config's default values to include the new SOUND effect and to match the newest version's syntax
• Improved the three display.betterhud.disable options to re-enable the respective features when set to false
• Improved the display.betterhud.as-default option to be reversible too
• Fixed a few typos here and there (mostly internal + debug messages)
• Removed fix-height option in favor of the new offsets
