add a way for title in titled view to be a link+issues

We are very close to having everything we need to create excellent basic blogging in core Wagn. Perhaps the only thing missing is the standard way of offering a permalink to a given post, which is to have the title of the post be a link to its page. One could Wagneer this into the form for blog entries, but this produces redundancy in feeds, showing the title twice (and with longer titles crowding a lot of entry content out of excerpts).
