[dev1031] Truly "Hardcore-friendly" NMs. Make us HUNT them.

@Gifthorse: I'm not in a terrible hurry. It could come "soon" or whenever they're not "stressed" anymore (or obviously, it could not come at all, but hope is good to have nowadays).
After all innovation pretty much always takes time to implement.

I'm quite sure it's not so burdening server-wise, as the game already has environmental collision detection (that ensures that mobs won't be stuck in the environment) and random pathing. The server load wouldn't be much higher than that of any normal mob (unless I'm missing some very big detail here, but I doubt it). I'm actually inclined to say that restricting a mob to it's territory may actually cause a higher burden on the server than letting it roam free.
