The part of the wizard where you add pieces to the board is still broken. The board shows up, but nothing else.
I inadvertantly broke this when I added the Betza-to-text converter. This uses castleRank to get the name of the piece that is castled with. But it tries to do that when there exists a piece that can castle in the piece table. But if that piece is not yet on the board (as it is in the Wizard, as this starts with an empty board) castlingRank has not been determined yet. I fixed that now.
