Now that we have this helper, we no longer need these stylesheets to
include a `body.controller-action` wrapper to scope all the styles!
Someday we should convert more of our stylesheets to this format,
instead of slamming them all into `application.sass` like we do now.
Ah, well!
I'm getting ready to add handling for "what if you don't *have* a
current password*??", so it seems like the right way to do that is to
just eject the controller and start customizing!
