Added option to put Black on the bottom of the diagram. Also a text "dot" diagram is added to make minor changes, but White remains on the bottom. A dot or space or "1" may represent one empty square on the dot diagram. Space is not allowed in the FEN line--it causes the rest of the line to be ignored.
Changes are in italics.
