Compares the best known tile improvement action with improving ptile with activity act.

		struct settlermap *	state
	)

Finds tiles to improve, using punit.

The returned value is the goodness of the best tile and action found. If this return value is > 0, then best_tile indicates the tile chosen, bestact indicates the activity it wants to do, and path (if not nullptr) indicates the path to follow for the unit. If 0 is returned then there are no worthwhile activities available.

completion_time is the time that would be taken by punit to travel to and complete work at best_tile

state contains, for each tile, the unit id of the worker en route, and the eta of this worker (if any). This information is used to possibly displace this previously assigned worker. if this array is nullptr, workers are never displaced.
