refactor code a bit to move connect setup into run.js of the specific server.  this will make it easier to figure out how to run servers both standalone and in the test harness

migrate to the connect framework for node.js, specifically this provides session management middleware

add support to top level runner to support server specific dispatch code (so authority can have it's own little server, for instance)

hacked up node.js test harness to run everyone on their own host/port and  to sub in ip/port combinations for hostnames.
