MAJOR UPDATE!

Added a derived class for the rare event of an un-authenticated IPSC,
this necessitated moving two global functions into the classese.

Changes to prepare this as a module -- all "user space" packets that
are received now have expliciet callback functions (handily located in
one place)

Moved the supporting characters into the ipsc sub-directory. The config
is the only likely one to be touched.

Improved some of the logging, but also commented it out to make things
run faster when it is not in use.
