scrabble: validate scoring & move generation against real GCG games

Browse Source 
Replay 17 real tournament games (cross-tables.com, including the 700+ club) and
check, move for move, that:
  - ScorePlay reproduces the protocol score and running total exactly;
  - the move generator produces every dictionary-valid played move with that score.

The GCG parser handles coordinates (across/down), blanks (lowercase), played-through
tiles ("."), passes/exchanges, challenge bonuses, end-game rack adjustments and phony
withdrawals ("--", un-applied). Uses the committed dawg/en_sowpods.dawg.
