Fixed

• The big blind now moves one player per hand when chairs are empty.
  Blinds are placed by position (TDA 2024 Rule 32, dead button), but the
  button did not move by that rule. Table::button_up moved it one chair,
  so with players on seats 0, 1 and 5 of six chairs, seat 5 posted the big
  blind four hands in a row; heads-up with empty chairs, one player posted
  it five times in a row. Dealer::start_hand moved it to the next
  occupied seat, so in the same three-handed game seat 0 never posted the
  big blind. button_up now moves the button until the big blind reaches
  the next player after the last big blind posted. The button and small
  blind can land on an empty chair; when the last big blind left, the small
  blind is dead. Heads-up, the button stays on the small blind's chair
  (Rule 34). Dealer::start_hand and SimTable both use it. With every
  chair taken, nothing changes. See
  DEFECT_044.
