Footnote syntax doesn't work according to Asciidoctor documentation?

[ShadowKyogre]

Hey everyone! Was testing DocGist to render some random documents I had written on an etherpad instance. It looks like that the asciidoctor version of the footnotes syntax doesn't work on DocGist. Here's the data I tested with.

The version of Asciidoctor used by docgist is woefully out of date. See #21 for the effort to get it updated.
