uifolders and uiallfolders cursors now setNotificationUri on
the appropriate uri. That uri is notified whenever:
- A folder is inserted, deleted, or modified.
- A message is inserted or modified (since this can affect
message counts).
This second one is still not quite right: there are some
conditions where counts aren't updating correctly.
While I was here, I renamed the notification uris to
avoid collisions between different versions of the app.
