When clicking on an unwalkable tile, the pathfinder will give up immediately and refuse to walk anywhere. This is
annoying when navigating terrain with many obstacles, as a walk will be interrupted many times. Instead of giving up,
walk to a walkable tile as close as possible to the destination, if that tile is within a specified number of steps
(currently 2) from the destination tile. Since the tile is returned that is first found in the search, situations
where the actor goes off on a tangent unnecessarily to walk to the nearest tile on the other side of a fence should be
avoided, at least in cases where there is a tile within the same distance on the actor's side of the fence.
