Pages now have accessible 'titles', sort of. A page's title is taken to be the value of the header that starts the page, if said header is on the very first line. (So this page's nominal title is 'New: Page Titles'.) The header level doesn't matter; a <h6> is as good as a <h1>, so long as it's the first line on the page.
This info is available only after the page has been rendered, in the new global context variable :wikitext:title. Fortunately for us, Atom feed entries can have their fields in any order, so we are free to generate <title> after <content>.
Why did I do this? First, it's suitably low rent, and second I decided I wanted some vague way to generate semi-real page titles in Atom feeds instead of the current full path to the page (ever so helpful and informative as it is).
