    A box specialized to show the ST/X about information.
    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
