* now ignoring if-modified-since if we failed an etag if-none-match comparison, per spec
* now including a hash of user id/nickname in most etags, so we'll update the view properly after login/logout
For API methods, checking the API-auth'ed user. (Many change results to include things like 'you're subscribed to this user' or 'this is one of your favorites', so user info is again needed)
There'll still be some last-modified stamps that aren't including user info properly, probably.
I changed the way that tag: URIs are minted, so we now use the right
base. Ideally most of these would use HTTP URIs instead, but for
now at least they use the right base.
* Mostly punctuation updates so that the same message is used consistently in all of StatusNet.
* Some cases of "Title Case" removed, because that does not appear to be used consistently.
