Include " w - -" and " b - -" in FEN notations

[Elucidation]

https://www.reddit.com/r/chess/comments/4b3h8s/that_felt_good/d15u5cySuggestion: one annoyance with these postings is that some chess interfaces reject the FEN because it does not include the color to move, castling, and en passant portions.
I suggest that the post include two copies of the FEN, one with " w - -" appended, and one with " b - -" appended. That will at least let the user pick one that has the right side to move and will be accepted by their GUI. They might still need to tweak it them for castling and en passant, but at least they can do that in their GUI once the basic position is entered.
You might even guess at the castling. Assume that if the king is on the original square castling is still allowed with any rook on its original square. Games where a king or rook move and then return to their original square are rare enough that this will be right most of the time. (Related issue #10)
That would match the convention generally followed in chess puzzles, which is that unless otherwise stated assume that kings and rooks on their original squares have not moved.

Two copies of FEN, analysis and editor are shown for black and white, as well as for both board orientations. Closing issue, revisit with better solution in #10 to resolve castling.
