Refactor: Moved AuthnRequest session storage to a new AuthnRequestSessionRepository to make testing easier and have a hard interface that obscures the implementation details.
Refactor: improve phpDoc
Remove commented out code for response signing and response verification test
Refactor: Added guard for sspmod_saml_Message::addSign IDE support
Test fixes: always bootstrap EB in the test bootstrapping. Unfortunately this creates a global variable with a closure that phpUnit falls over so disable backing up of globals.
Issue #64, fixed tests.
Fix for issue #84, X-Forwarded-For header instead of REMOTE_ADDR as IP address source. (still missing test)
