- Make opml as a reference in ItemAcceptor(), same way as we do for generatorHtml.
- Remove ItemAcceptor.getHost() and ItemAcceptor.getPort(), we just need local access now.
- ClientThread.doOpml() no longer throws an exception.
- Make ignorefutureitems public static final, remove the not static getter method.
- Access Control.ignorefutureitems directly, there is no getter anymore.
