[squeak-dev] PAPS -ParrotTalk Automated Protocol Selection

- I ported SSL  and SSH , onto ParrotTalk's framework, along with a new supporting ParrotTalk , including the supporting Telnet  and PseudoTTY changesets from Ian Piumarta . Complete delayed credit due to Ian. I harvested the ProtocolState from Ian many, many moons ago and completely forgot to credit him and lost the pointer. Well, in porting Telnet, I rediscovered the original source. I ensured its definition within ParrotTalk, with a few changes I depend on. Thanks Ian!
I ported initial attempts to subclass an important stateMachine, from each of SSL and SSH, to be rooted at ParrotTalk's SessionOperations. More work is needed, including defining active frameSpecifications that can ddetect appropriate frames for these new Protocols, in a new FrameAnalyzer, to be used by the new SessionProtocolSelector. The current hierarchy of SessionOperations as follows:
 SSL-rww.20.mcz -
 SSH-rww.13.mcz -
 ParrotTalk-rww.30.mcz -
 Telnet-rww.105.mcz -

That would be a powerful capability.
