Subject: [PATCH] TNT: Damage mobs, knock back players
We apply punch damage to mobs caught in the blast radius, as
this code previously only hurt players.
We "move" players back 1 node if they're caught in the blast, and
slightly up. We can't "eject" players due to missing API code to
support that, unfortunately.
