Fleshed out Scheme primitives

* Moved board specific functions from othello.h to new othello_board.h

* Removed unused function pointer for player moves

* Added prototypes in headers for SCM functions, including
  scm_get_current_player,

* Made get_winner accept a board and current player. This is useful for
  predictions to see if some move would make the other player a winner.

* get_winner also writes the players scores to provided pointers.
