Add a silly script to add a widearea node to the DB. It does the nodes

table, virtual nodes and the interfaces table. Also runs named_setup.
This script is only good for pcwa and pcron, and gets run from the web
interface when a wa node checks in for the first time.

With work, it could be a general addnode script.
