    Reinsert some missing screen-clears.
    
    I just introduced the 'first_draw' flag in the midend, which should
    force a screen clear whenever we draw a puzzle with a fresh drawstate.
    But in fact there were several places where the midend replaces the
    drawstate and I hadn't set that flag to true.
    
    In particular, a user just reported that when you press 'n' for a new
    game in an existing Magnets window, the new puzzle's clues are drawn,
    but any old clues in places where the new puzzle doesn't have one is
    not _un_drawn. (Because Magnets has no code to undraw a single clue -
    it never needs to!)
    
    Added a set of first_draw wherever we call new_drawstate, which should
    make this reliable again.
