Add functions turns_to_enemy_city and turns_to_enemy_unit to estimate the
time needed to reach the enemy city/unit, possibly with the aid of
ferryboats.  Also add the function best_role_unit_for_player to get the
best ferry type available to a player.

Patch was improved following useful suggestions from Raahul Kumar, Per
Mathisen and Mike Kaufman.
