I don't think there's necessarily anything wrong with using non-ASCII
characters, since UTF-8 is basically the de facto standard. There's no
reason to mix a small number of curly quotes into a configuration file
though, so I've replaced them for consistency.
This way we no longer have people confusedly editing mediagoblin.ini
when they meant to edit mediagoblin.example.ini. Hopefully it should be
a lot simpler.
