feature update request re: poking the crusher

[Roomba]

I think the current amount is fine. Bleeding in general is still not really all that balanced - see the thread about the tranq rifle, for instance. The most common source of limb removal is getting caught in an explosion, in which case you likely have to deal with dragging yourself to medbay while limbless and caught in an airless corridor. There's no need to deal with bleeding damage on top of that.
