    [EXPLORER] Implement rudimentary uVersion management, and notification balloons.
    - uVersion will only be truly useful when Vista+'s V4 style notification icons are
implemented.
    - Balloon notifications do not yet support queuing and auto-closing.
    - Force the notification icon tooltips to always show even if the taskbar isn't
foreground.
    [ROSCTRLS.H] Implement CTooltips class which manages a comctl32 tooltips window.
