Jabberpy is now actively maintained again.  It has moved a
bit and there are places where we may need to update our
code.  Two changes that should happen that I've noticed so far:
- the Protocol object builder helpers no longer need to
exist, as Message, Presence, and Iq now take the right
arguments (though they might be spelled differently, so I
can't nuke build_* functions yet)
- build_reply -> buildReply.  This should be easy.
