Prior to this patch, links found in KNewStuff content descriptions were ignored and both unclickable and unselectable. With this patch, clicking a link will launch the default browser pointed at that link. Currently this is limited to KNS content, but it would be reasonably trivial to add to other content types as well, but thought it would be best to discuss on one type before doing them all at once.
This patch further fixes a minor oversight in the BBCode neutraliser in the KNS backend (which would previously eat chunks it was not supposed to, such as parts of URLs).
