Patience Revisited PalmOS

I think that a fair improvement in game usability would come to this small
modification to the criteria for the auto move to pile in frecell game.
As it happens on windows freecell, cards are automoved to the pile only if
they are no longer needed on the pile, that is when the lowest card of
opposite color is equal or higher...

In other words, the 5 of hearts is no longer needed if both the 4 of spades
and clubs are not in the game.

it only should be a matter of an if clause, but I couldn'd find the piece
of code that controls the auto move.

Thanks

P.S.
I might have switch the pile and stack words, I never remember which one is
which!!
