Make apply_move accept a board as a parameter.

This was how it originally was, but I changed it to use a global
variable instead. I want to be able to use the apply_move function in
the is_valid_move implementation, to have all the logic for checking if
a move is valid in one place.

Moved the apply_move function out of board.c, since it no longer
needs a direct reference to the board.
