Fix an off-by-one (in x and y) position of villages in the village list of map

- This fix bug for reachables villages to teleport (incorrect black stripes)

- incorrect status-bar info of number of visible villages

- possible bad AI decisions about villages (where they are and owned or not)

- waa still need to test "store_villages" (possibly affected/fixed)
