    New specialist backend function, set_public_desc().
    
    This is the counterpart of midend_supersede_game_desc(): in the rare
    case where a puzzle needs to set separate private and public game
    descriptions, this method is used during game reload to allow the
    contents of the _public_ description to affect the starting game
    state.
    
    I hope this will be even less often used than the rest of the
    Mines-specific bodges. But Mines itself _is_ about to use it, in the
    next commit.

    Mines: mark the first click when undoing past it.
    
    One hole in Mines's "you never have to guess" story can occur as a UI
    accident, rare but possible: if a user clicks on a blank grid causing
    a game to be generated, and then (perhaps absentmindedly) presses Undo
    to return to a blank grid, then the mine locations are now fixed, and
    clicking somewhere _else_ might kill you, or open a single square,
    or (perhaps even more confusing) open a region from which the game
    can't be solved.
    
    This commit does not stop the user doing that, but makes it clear when
    they did. Now, after the first-click location has been selected and
    the mines have been placed, if you undo the first move, the location
    of your original first click will be marked with an X. Then if you
    click somewhere else and find something confusing has happened, it
    will at least be more obvious what's going on.
