Improve the layout of XineConfigDialog

Properly display the description of each of the settings.  Also,
reorganize the layout so that it uses layouts rather than VBox/HBox.

The TabWidget class has been removed in favour of the standard
TQTabWidget class, as the different behaviour doesn't make a notable
visual difference.
