[keycloak-dev] initial PL SAML fork

I forked picketlink-federation and some of picketlink common into the keyclaok-saml-core project. I did not refactor really anything, but I did gut tons of stuff, sts, XACML, and all the WS-*/SOAP stuff, handlers. I tried to keep it solely focused on just a parsing library. I also renamed, consolidated and moved packages. It looks like we still have a few dependencies left, but we're getting closer to Picketlink-less Keycloak.
