A customized `make-channel-socket-server!` that uses Node.js with
Macchiato as the web server.

Wraps a generic node Sente handler to work with Macchiato.  This
remaps some keys of a Macchiato request to match what Sente and the
generic node adapter are expecting, calling `handler`.  The generic
node adapter will call the appropriate methods on the Node.js response
object without using Macchiato's response function.
