Sceneri title changes

Created by: taggart

Here is a collection of scenari related stuff, mostly title.gettext changes to make things more consistent. There are a couple changes that could be considered related to #362 where an authenticated version of a type didn't exist. In those cases the patch adds one, but maybe it would be better to add the authentication to the existing non-auth version?

Feel free to just cherry pick whatever makes sense and also let me know if you'd prefer that I break things up into multiple PRs.
