* The BLIPConnection receivedRequest: delegate method now returns BOOL. If the method returns NO (or if the method isn't implemented in the delegate), that means it didn't handle the message at all; an error will be returned to the sender.
* If the connection closes unexpectedly due to an error, then the auto-generated responses to pending requests will contain that error. This makes it easier to display a meaningful error message in the handler for the request.
