diff.mjs: Allows showing subtraction

    Adds "Show Subtraction" button to allow seeing only the difference
    between two texts.
    When selected and combined, user can see only the characters or
    words that were added. If not combined, with either removed or added
    but selected, then nothing is displayed.
