Save total material with setup position

The total-material counter R, which determines the game stage, was not
saved with a setup position, so that 'undo' could mess it up. The piece
counters for each side, in pl[], are now saved in a loop, rather than
just the WHITE and BLACK element, and is extended to 32 elements.
