Forget nodes from the lists when they leave the circle in the Pure Data version.
Tweak Python node forgetting code - removed old state ID reset to zero for leaving nodes.
Fixed a bug in the Python implementation where it was still trying to compare checksum algorithm name which is now removed.
Python implementation - rebroadcast debug message includes state name.
Pd implementation - got state ids being broadcast when state checksums don't match on the tick. Got states being re-broadcast when older than two ticks and missing froms somebody's state-id broadcast.
Nit - log level for state checksums.
Pd - removed inital state stuff. Messages being rebroadcast correctly to nodes who don't have the latest.
