Fix bug of 1994/dodsond2 wrt arrows stolen

The problem was that one could never get their arrows back from the
robber if they ended up shooting an arrow because that means the number
of arrows stolen could never be the right number of arrows. Now if the
number of arrows stolen (when you encounter the robber) is equal to the
number of arrows you found - the number of arrows you shot you get
arrows back: as long as the robber took some of course. At this point
the counters are reset so that the check does not fail the next time.
Previously it compared to just 3 as there are only three arrows. But in
the alt version (which was helpful to test this out more) this is
obviously a problem even if it wasn't in the original. It was however a
problem in the original because if you shot an arrow you could not get
them back even if you have zero and encounter the robber. Of course now
the check has to verify first (&&...) that the number of arrows stolen >
0 as otherwise the variables could get messed up.

This should actually complete 1994/dodsond2 unless of course I missed
something/made a mistake here.

-A (mis)feature is that one must have had all arrows stolen in order to recover
-all the arrows from the robber. This means that if you end up shooting an arrow
-you can never recover all the arrows from the robber because the count of arrows
-stolen can never be high enough. There are a number of ways this might be fixed,
-some of which Cody notes:
-
-- If you have zero arrows and you come across the robber you could give them all
-back. This is not correct though because if you never had that many arrows you
-would end up getting arrows back that you never had in the first place.
-- A new variable, an `int`, could be added that keeps track of the number of
-arrows you have fired and then if you come across the robber and they took the
-number of arrows with the difference of the number fired then you would give
-back how many (the difference) the robber stole rather than all the arrows. This
-would be the right approach but there are certainly other ways to go about it.
-
-A tip is that the number of arrows stolen is `l` and the number of arrows you
-have is `i`. For the alt version that Cody added the starting number of arrows
-is in the constant `W`, defaulting to 3.
