seperate files for responder and initiator tests
test file that shows other participants leaking info has an effect
general code clean up
performance improvement: initiator and responder tests now run in ~10s
Added INITIATOR_TEST and RESPONDER_TEST macros to the identity hiding
mpv file that can be used to selectively test the anonymity of the
initiator or the responder.
Changed identity hiding test to work as a two stage process where
participants with fresh secure secret keys communicate with each other
and other compromised participants. Then the attacker is asked to
identify the difference between two of the secure participants as on of
them acts as a responder.
