[Code-review] review: Gadget debug branch

[Dafydd Harries]

This seems like a good idea. A slightly different approach is to use prefixes,
something like:

  def log_send(msg):
      log.msg(''.join('>>> ' + line for line in msg.toXml.splitlines()))

  def log_recv(msg):
      log.msg(''.join('<<< ' + line for line in msg.toXml.splitlines()))

There's code that does this in here:

  http://git.collabora.co.uk/?p=user/daf/mingle.git;a=summary

It actually goes a bit further and applies colours to messages according to
type, but this doesn't necessarily interact very well with Twisted logging.

I'm not particularly attached to either style.
