[Freeciv-Dev] ai should build more aqueducts

["Michael Kiermaier" <michael.kiermaier@xxxxxxx>]

i realized that in the current cvs the ai nearly never builds aqueducts.

just watch an solo ai game. in let's say 1700AD there are lots of size 8
cities and lots of aqueduct -needed messages.
and if there are a few cities bigger than size 8 they have size 12, lacking
a sewer system.

i think this behavior should be changed somehow.
