In the settler management agent (customizable auto settler with city
founding ability) I scan the whole known continent for a good spot if
a settler is without work. You also can't cache the results from turn
to turn because there may be a much better spot just expolored by
another unit. So I know this needs a lot of CPU but you can ensure
that it is the best spot possible at this time. I will see how much of
this can be optimized but fast path finding/warmap/goto functions will
help a lot.
