Support Paste style configuration

[lvqier]

I have to config python-social-auth like:
SOCIAL_AUTH_AUTHENTICATION_BACKENDS =
social.backends.douban.DoubanOAuth2
But the Paste style would like:
social.auth.authentication.backends =
social.backends.douban.DoubanOAuth2

Sorry?

@lvqier configuration is loaded by whatever framework you're using... That looks like ini style configuration to me. Is your request to support ini configuration of PSA?

@jaitaiwan Yes! It is raised by pyramid_app.
