Allow users to change page linked to in the "announce" bot posting
Created by: edg2s
The "announce" bit posts a link to the wiki's Main_Page, however this is often not the best place to start testing a patch.
We should add another input that takes a valid title path, e.g. "Talk:DiscussionTools" and link to that page instead.
We may also want to allow more complex URLs like "Special:UserLogin?returnto=Talk%3ADiscussionTools" for patches that require login.
