[Freeciv-Dev] three little suggestions

[Tuomas Airaksinen <tuma@xxxxxxxxxxxx>]

1)Whether to show or not to show the shadowed fog of war in client
should be optional (set from local options dialog).

2)It would be nice if settler/engineer (optionally) would carry a GRID
that shows area it will be able to exploit after building a city.

3)Maybe it would more realistic if explorer would see further than other
units.
