Subject: [PATCH] Fix re-appearing of board markers
The board markers could reappear after a machine move, after the already
had been cleared at the end of the previous user move. This because
HoverEvent() could restore them from the copy it keeps during hovering.
Now clearing of the board markers also clearse baseMarker[][], which had to
be made a global for that purpose.
