Added more readable printout of moves.
Add a CFLAGS variable to the makefile.
flushing the output and got rid of getchar().
Add the 'display-solution' program.

It is taken from:

https://bitbucket.org/shlomif/fc-solve/src/9732f6e654bd69fcf7aa563ce658641cc5b9f9d1/cpan/Games-Solitaire-Verify/Games-Solitaire-Verify/script/play-and-verify-klondike?at=master

What it does is replay the solution, while verifying that it is correct
and display it in a more user-friendly manner, with full boards at each
time and which card is being moved.

It requires Perl and some CPAN modules including the new version 0.1200
of https://metacpan.org/release/Games-Solitaire-Verify .
