[x] Support gists that have been forked via github. This means we have to get rid of gist_id and gist_url in the data package, instead setting the values dynamically.
[x] UI work to show that a given gist has been forked
[x] Fork button on projects owned by someone else
[ ] Easier ways to look at other peoples projects (helped by #105?)
Breaking this down into tasks:
gist_id
andgist_url
in the data package, instead setting the values dynamically.
