Each Scheme's user detail under $auth.user['schemeName']

[bramburn]

What problem does this feature solve?

Most login may have 1 user with many social platforms.

- user
-- Facebook
-- Github
-- etc...

currently the auth allows for 1 user and 1 platform access via $auth.user

Would it not be beneficial to allow access to further information such as Display pic, stats or handler name from different platform accessible?
So app owners could use $auth.user['facebook'] to gain access then.

What does the proposed changes look like?

changing the auth.js setUser to include further attr for different strategies.
