Fix variant switch on PGN loading

When the PGN specified an essentially different variant, the
piece bitmaps were not properly adapted, because the switch was done by
calling InitPosition(), rather than Reset(). (The latter would destroy
the PGN tags info.) We now added an explicit call to ResetFrontEnd(),
(which is normally done from Reset()).
