The settler problem is due to the AI favouring production over food need. Read
the advdomestic patches I sent in to the mailing list, or apply the
corecleanups 13 and just read advdomestic.c.

Ross seems to have a partial fix. He makes it favour setttlers when the number
of cities is fewer than 6. It seems to me basing it on available land mass
would be better.

We could build workers based on the minimap idea you had. The workers we need
is based on no of umimproved tiles in city radiuses, the amount of time it
would take the workers we currently have to improve them, aargh it gets hard
already.

Simple idea: we build one worker for every 4 cities. As no of tiles left
umimproved in city radiuses drops, we lower production.
