Fixes #344, #413, #513, #514, #700, #705, #738; Refs #735

• Nit's command line is extended to accept a port number on which to run its
  webserver.

• The transport layer of Athena is replaced with a message-queue based
  mechanism. This supports gap and duplicate message detection, allowing the
  server to leave the page "connected" for a short while even if a client
  abruptly closes its connection(s). This should provide greater stability in
  the face of poor network conditions and various kinds of proxy misbehavior.

• All messages sent from the server while synchronously handling a message
  from the client are bundled up and sent in a single response, rather than
  putting each message into its own response. Likewise, messages sent from the
  client while synchronously handling a message from the server or synchronously
  handling a DOM event using <athena:handler> will also be bundled up in one
  request.

• Only one transport resource instance is created per LivePage, instead of
  one per request.

• The guaranteed namespace-aware getAttribute helper has been moved into the
  runtime support code.

• Several problems with error reporting on IE in the test suite have been
  fixed.

• A lingering usage of MochiKit Deferreds has been removed.

• Escape is now captured and handled with an explicit close message.

• If a page is unloaded because the user navigated to another page, the
  disconnect dialog is no longer displayed.

• The client-side debug log displays slightly more nicely.

• Radical once again avoids using active channels and constructs cacheable
  URLs for javascript modules.
