    A box specialized to show the ST/X about-information (also usable for Applications).

    As a speciality, this box automatically closes if left

    alone for a while.

    Can be subclasses for your own aboutBoxes; to do so, redefine

    #defaultIcon and #aboutText.

    examples:

        AboutBox new open

        AboutBox new showAtPointer
