The additional filter token introduced 404's for bookmarked feeds;
now the old URLs are re-added and their actions forward the requests
to the new handlers.
Another small change removes a double assignment and puts the
"All Updates" link in the template on top to separate it clearly
from the other filters.
This commit closes issue 605.
The basic building block is here with the feed of the timeline, it is
rather easy to add the feed other elements based on this work. This will
require iterations and polishing.
