I've changed it so that XML and HTML files that don't have an explicit
manifest will get fetched from an appcache if there is one from the same
origin. (If someone _adds_ a manifest, then the cache will get updated
with that new URL, and if the user goes back to that page, then it'll fail
to load from the apocache since it is now foreign.)
