Wiki timeline URLs should contain the version

[sudonym@…]

URLs constructed on the timeline page and rss version for changes to Wiki pages only contain links to the Wiki page that was changed, not to the actual version of the Wiki page. This leads to non-unique URLs in the rss feeds which break many readers, as well as having links on the timeline to non specific Wiki page versions. This patch corrects this issue:
