Create a root node on the open internet with a fixed IP address

[ntoll]

Probably using #34

This will be the IP address / port made public for those wishing to join the network. For the purposes of debugging, information gathering we'll probably need:

• Some mechanism for checking current availability (use a third party service)
• A schedule for backing up the routing table and local dictionary
• A simple mechanism for bringing up and restoring the node from snapshots in case of failure
• A way to generate interesting stats about the interaction with the wider network:
  • Number of unique peers seen
  • Traffic volume
  • Number of user's encountered
  • Number of ITTT like triggers fired
• General local performance of the node (for the purposes of performance review)
