Implement an account mangamement system with GitHub auth

[bcardarella]

Because there will be voting and submissions I'd prefer to limit to some public identities rather than anonymous auth.

I don't think we need any information from the individuals beyond GH auth.

users:

• what ever columns are necessary for GH auth

Depends on #1

[iagocavalcante]

Guess this information is enough. What do you think?

%{
          uid: Kernel.inspect(auth.uid),
          email: email,
          avatar: avatar_from_auth(auth)
   }

[bcardarella]

@iagocavalcante are these from GH auth? If so then we don't need email. We just need their GH username and whatever token their oauth provider gives

[moomerman]

Is the oauth token required? Would only need that to do something on their behalf on GitHub. Minimal requirements probably the username and the UID (in case they change username).

[bcardarella]

Probably not, we just need to persist the auth session.
