Changes ipcs brute mods and fixes some issues with their external organs (#2894)

-removes the brute reduction from the regular baseline, because robotic limbs already have those
-reduces the industrial brute resist from 0.5 to 0.8, because again robotics limbs already have some
-fixes industrial and shells head not being tagged as vital and makes their max damage be equal as other external organs
