Fully stateful spring-web-social

[activey]

Hi :)

Just wanted to share some of my latest achievement when it comes to using spring-social-web in fully stateless manner.

I've been struggling with using spring-social-web module and could not accept fact, that for some reason it still makes it impossible to get rid of HTTP session usage so I "forked" spring-social-web, redesigned it a bit and created a Maven artifact that maybe some of could leverage of. Module code is available here: https://gitlab.com/activey/spring-social-web-stateless, example code usage can be found here: https://github.com/activey/spring-social-web-stateless-demo.

I'm not doing it as a merge request because it will probably take some time to pull it in...

I've added some small readme in demo project just for sake of any details at all (I'm kinda in a rush ...).

spring-social-web-stateless itself is based on original spring-social-web with some stuff stripped of, and some stuff added in.

For now it supports only OAuth2 flow but if there will be some interest in project itself I can try to spend some more time on that and add OAuth1 support, who knows.

Feel free to do some pull requests and experiment with code.

Cheers! :)
