More rewrites (and code stops):
- Renamed a lot variables towards UNL (universal node locator) which allows not
  just ip:port locators but in a more URI-like style: protocol://address[:port]
  'address' could also be a fax number where you want to establish a
  "connection" to by sending the serialized base64-encoded data to.
- Renamed methods to reflect latest rewrites
- Updated core to latest changes
