[Plugin: Warcraft News] Wowhead links

Perhaps I should have been more clear: ATM only the items are rewritte, because the achievements link to the guilds or chars achievements page with their own progress. If I would link that to wowhead, you would see messages like “Completed step Blackbelly Mudfish of achievement The Limnologist.” without being able to see the actual progress. But I consider making it an option in the next release.
