  { Opt/Initialise
    The user opened the options dialog. Modules should do whatever initialisation
    they need and call opt/addpage one or more times if they want pages displayed
    in the options dialog

    lParam=0
    addInfo should be passed straight to the wParam of opt/addpage

    Must only be called during an opt/initialise hook
    Adds a page to the options dialog
    wParam=addInfo
    lParam=(LPARAM)(OPTIONSDIALOGPAGE )odp
    addInfo must have come straight from the wParam of opt/initialise
    Pages in the options dialog operate just like pages in property sheets. See the
    Microsoft documentation for details on how they operate.
    Strings in the structure can be released as soon as the service returns, but
    icons must be kept around. This is not a problem if you're loading them from a
    resource.
    Prior to v0.1.2.1 the options dialog would resize to fit the largest page, but
    since then it is fixed in size. The largest page that fits neatly is 314x240
    DLUs.
