fixed problem with setConfig(). if the new config didn't 

include a screen that was already connected under an alias
then that screen wouldn't be disconnected and removed from
the screen list until the screen voluntarily disconnected.
at that time removeConnection() would assert because the
screen name would not be found.  now using the canonical
name in the protocol object as well as CServer.  this
allows setConfig() to always detect removed screens and
disconnect them.
