Spiky monsters should hurt the player when attacked

[coolio]

Spiky monsters (porcupines, spiny frogs, hedgehogs) should hurt the player when melee'd - at least when the player is unarmed.

Jellies already do this and it really is what one would intuitively think that would happen (ever tried punching a porcupine? ouch!)

Also, devs: Add hedgehogs in the game

Pretty sure this is planned but just not yet coded. I know Cryptic is working on a huge fight.cc overhaul that would cover more varied on-hit effects like this, although we should probably have had spines at least for porcupines in 0.8 - not sure if there's time now.
