Qt: Remove GraphicsWidget class

The old tooltip description box used GraphicsWidget to provide shared
code to the Graphics config panes for adding descriptions to their
settings.

The description box has been replaced by BalloonTips and serves no
further purpose, so remove it and have the Graphics panes derive from
QWidget instead.
