TODO:

- add a c4_abort_auto_move() function (for use with c4_poll())

- add c4_init_from_string() and c4_save_state_to_string() functions

- add a c4_undo(int nMoves) function
    - keep a stack of states by calling c4_save_state_to_string() once
      per move
    - c4_undo() can pop from this stack and call c4_init_from_string()

- rewrite online Connect-4 game to use Ajax
