The patch seems good to me.  Per's government-effects patch (12757)
touches this same code (or should) and kindof breaks or changes this
behavior (I don't fully understand how though; you'd have to ask
Genevieve or Per).  I'd say we can commit this patch first though.

In general, I don't fully understand how happiness, celebration,
unhappiness, and disorder work.  I know I've said this before, but: is
there some documentation on this that anyone can point me to?  If not,
can someone write some?  It's probably best to put it in the comment for
city_celebrating() and reference it in all the other such functions
(city_happy, etc.), but it would be okay in doc/README.* as well.
