Mines-Perfect

Please add a "stage-n" (iterative) solving algorithm, as
there are instances (very rare of course) where the
existence of a mine is dependent on the analysis of
every single unknown space(that is touching a known
numbered space. I am going to try to implement this
into your source; I'll let you know if I am successful.

Note that if I am successful (and the algorithm runs in
polynomial time in terms of input size n), the P=NP
problem will have been solved.
