New dupe emotions (and lack thereof)

[x4550]

- Hunger response is completely ridiculous.  With that face?  Come on.  Maybe, maybe, if they're starving to death, they should make that face... but to do it all the time?  It's not believable.  

- Bladder response is ridiculous.  Maybe, maybe if they're about to wet themselves they should make that face, but not all the time.

- Dupes don't smile anymore!  It used to be nice:  they would smile on their way to do something, then have a serious face when they were doing it.  That's believable.  And relateable.  Now it's just so bleak.  Why, again, am I working to sustain these creatures if their lives are so dismal?  I'm starting to forget.
