- can collect sea resources near coastal city, with a range limit depending on techs and buildings
- some resources (stone, copper, iron, salt) are available in small quantity on some terrains
- the plot tooltip now show those resources (and those already available in features like wood and plants in forest)
- moved all buildings from the Harbor District to the City Center, they can only be build in coastal cities
- add Fish Market, a building unlocked with Sailing that can convert Fish, Crabs and Whales to food (can be build anywhere), the normal market can also convert those resources now.
- tweak down materiel requirement for Settler
- the central square (free building added on city creation) can now convert a few resources per turn to food
- add tooltip info in the building tab of the city panel
- resources can't be harvested anymore
- no population prerequisite for settler (the supply mechanism is enough)
- try another fix for unlocker buildings being pillaged on city capture as the previous one was failing
- fix chariot and swordsman equipment not working and displayed as "unknown" (all other units with equipment requirement still show "unknown" as their equipment is not set yet)
