Tracks: make sure moves are valid in execute_move()

Tracks allowed moves in execute_move() that shouldn't have been allowed,
like changing the state of the edges of the board.  This moves couldn't
be generated by interpret_move(), but could be loaded from a save file.
Now execute_move() uses the same ui_can_flip_*() functions as
interpret_move() to decide whether a particular move is allowed.  This
should prevent some assertion failures when loading corrupted save
files.
