Here's a patch for the in-game help.

I put a lot of info about city centers into the "terrain improvements"
section.  If there's a better place for this to go (I don't think there
is, yet) it should be moved there, and the terrain improvements section
should refer to it.

The online manual should also be updated, but not by me.  Come to think
of it the "online" manual should be in CVS somewhere, and should
probably be distributed with the game.
