Auth: Github

[hunvreus]

Please reassign to the one work on this.

The module carcass-auth is in this repo for now. The one who's working on this will need the permission.

Details:

• Please build and send me pull requests.
• Please use passport-github.
• I only need the login process. Please do not consider session supports.
• Note that the login process involves 3 characters: client, server and Github. You'll need to setup Github first and simulate the client with tests.
• Build an auth plugin in /auth and optionally a test application in /test/fixture/applications to expose some test info.
• The client will need to be redirected and input info on Github. It's not easy to do it with tests so you can test it manually and then do it with tests. Not that the test is a requirement.
