TPB feed is a good example <http://rss.thepiratebay.sx/blog>. Now supports ampersand in feed, using the "recover" mode in etree.parse. Broken utf-8 strings in feed are now also supported.
This is a huge change. Feed parsing is now done in a separate file, much cleaner. The code of the lib tends to repeat itself a lot though. It should be possible to improve it. Code should be more stable.
