[keycloak-dev] Pulling in reusable stuff from Identity Broker

I've started to pull in reusable stuff from Identity Broker, and at the same time done some refactoring. It's here: https://github.com/stianst/keycloak/tree/idb-pull It's a work in progress at the moment, but the general idea is to pull things into 3 components (all jars): * sdk-html - sdk for html and js applications, this includes the login and registration forms * social - social spi + google and twitter implementations * ui - web app to create/manage applications/realms/users
