Is it fine to add undocumented option to initializer.rb?

[tackeyy]

As I found the undocumented option which is about Github's scope with external module in Github OAuth. I think it is better if below code is inserted in initializer.rb, because it takes time to find the option out if someone who uses Github OAuth with external module and want to manage the Github's scope.

config.github.scope = 'user, repo'

I don't see any problem adding the scope to the generators, personally. Adding a note above the Github values though saying why/how to use the scope would help users understand why it's there (and why or why not they should use it). Feel free to open a PR, where we can discuss the finer details.

Also, if you wanted to update the docs in the wiki at all your help would be greatly appreciated. :)

Thank you for the reply. As I opened PR #50, I close this issue.
