(svn r7823) -Fix (r7384 / r7368 / r3757 / r7388): News windows could still cause crashes because
DeleteVehicleNews shuffles around _news_items which can wreak havoc with the NewsItem*
of a currently open news window. While here also correctly update _current_news and
_forced_news for the same reasons. Should really work now.
