Fixed anti combat log code

Improved damage callbacks and added missing ones for vehicle collisions
and explosions.

Improved combat log code to be a bit more accurate.
Improved knockouts, fixed body preview UI bug

Fixed the body preview UI popping up when taking damage.

Improved knockouts to just add the duration if the player is already
knocked out instead of playing the animation again.

Moved health based knockouts to the /Player/Core script as it's not
directly related to the knockout mechanics.
