transform: Explicitly bind LiveReload to server port

If hugo server is run on port 80 or 443, LiveReload does not
correctly bind to the same port, instead using port 35729.
This commit adds functionality to inform LiveReload of the
correct port to bind to.

See https://github.com/livereload/livereload-js/issues/16

Partially contributed by Jeff Minard (@chuyskywalker).

Fixes #2205
