Allows Alt+click turf contents listing to be used on any tile you can see

Created by: Exxion

Someone clearly intended this to only work on adjacent tiles, but I can't figure out why. It doesn't let you do anything right clicking doesn't already let you do anyway, but it doesn't have the lag problem associated with right clicking.

Now it still only works on tiles you can see. If the inspected tile leaves your vision due to distance, darkness, or obstruction (or anything else I didn't think of), the list of stuff disappears, like already happens if you move away from the inspected tile.
