Damage check before de-limbing in explosions.

[PenguinsMeep]

Had the same problem when a traitor mindslaved me, and ordered me to ride a forkfift with a bomb and scream "GHOST RIDE THE WHIP" and blow up. Modified AI went through the radio frequencies and blew the forkfift up just as I boarded it. I had industrial armor, received no damage apart from my leg falling of smoothly. Traitor got gibbed.
