I've rewritten the Empath PERC CRITTER command.

1) The output is now a little more flavorful.
2) The ability now distinguishes between living, construct, and undead. Cursed-but-not-undead fall under living.
3) You get a token amount of Empathy experience if you perceive a non-construct. There's a timer on how often you get experience, and it's per Empath not per creature. I may adjust it up a touch, but it's meant to be a small boon for new Empaths, rather than a reliable training mechanism.

I am concerned that, due to how it tracks what is undead, there may be false positives or false negatives. Please play with it and let me know if any show up.
