The `IkiWiki::pagetitle` function does not respect title changes via `meta.title`. It really should, so that links rendered with `htmllink` get the proper title in the link text.

has no title, then A will display the link as "B". Now page B is modified
and a title is added. Nothing updates "A".
The added overhead of rebuilding every page that links to B when B is

That could be hundreds or thousands of pages, making interactive editing
way slow. This is probably the main reason I had not attempted this whole
thing myself. IMHO this calls for some kind of intellegent dependency
`pagetemplate` hook. (Although this would eliminate handling of
`title_overridden` -- but that is little used and would not catch
all the other ways titles can be overridden with this patch anyway.)
