* HTML cleanup for the router console (thanks!)

    * Lay the foundation for 'client routers' - the ability for peers to opt
      out of participating in tunnels entirely due to firewall/NAT issues.
      Individual routers have control over where those peers are used in
      tunnels - in outbound or inbound, exploratory or client tunnels, or
      none at all.  The defaults with this build are to simply act as before -
      placing everyone as potential participants in any tunnel.
    * Another part of the foundation includes the option for netDb
      participants to refuse to answer queries regarding peers who are marked
      as unreachable, though this too is disabled by default (meaning the
      routerInfo is retrievable from the netDb).
