* Re-enable lookout

Reasons:
* More content in Sailors
* Perhaps we get a proper range concept sooner or later
* FIFE has a working Fog of War in their development branch
* Random maps can have larger islands which players want to claim early
The current best practice to achieve this involved building storage
tents literally everywhere which is not something we should encourage.
