TODO
----
* Make KCMNewsTicker care about the order of the news sources when loading
  them - currently, the items are inserted in the list alphabetically, and
  QListView::setSorting(-1) doesn't seem to help either. :-/
* Make the default list of news sites dependant of the configured language.
* Get our own icons instead of just copying KNode's.
* Make it possible to associate an icon with a news source, so it's easier
  to see where a headline comes from as it scrolls by
* Make the speed at which the mouse wheel scrolls the text configurable.
* When dragging leaves the window, create a URI Drag Object to make it
  possible to drag the headline to an already open browser window or
  copy/link it to/on the desktop
* Extend the DCOP interface to make things scriptable
* Centralize the default values, currently kcmnewsticker and knewsticker are
  somewhat out of sync. :-(
