Fixed returning copy of board.
Begun writing 'eval_to_consequence' function - added test in 'make' func. for only supplying even numbers.
Changed Player'id's to include the Non-existent player, due to Board design pattern.
Added new cases for the None-player.
Fixed replmodloader - not allowed to change away from loaded dir.
Made 'move_all' func. - not to be used directly by users of Board module (becomes hidden later). Tested.
