Add a setting to allow anonymous access to individual gists while still RequireLogin everywhere else (#229)

* Add a setting to allow accessing individual gists without auth

This is a middle ground between the existing setting "Require Login",
which requires login to do anything at all, and having it off, which
shows a public list of gists and more generally allows discovering info
about the users/gists of the instance without login.

The idea of this setting is that it is "require login" for everything
except individual gists.

Fixes #228.
