JID's are not __deepcopy__ able.

[jbzdak]

When I tried deepcopying object containing a JID following error occoured.

In [1]: from sleekxmpp.jid import JID
In [2]: from copy import deepcopy 
In [3]: deepcopy(JID())
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-3-89cd7190e165> in <module>()
----> 1 deepcopy(JID())

/home/jb/.virtualenvs/silf-backend-commons/lib/python3.3/copy.py in deepcopy(x, memo, _nil)
    164                     reductor = getattr(x, "__reduce_ex__", None)
    165                     if reductor:
--> 166                         rv = reductor(2)
    167                     else:
    168                         reductor = getattr(x, "__reduce__", None)

TypeError: 'NoneType' object is not callable

I have no idea whatsoever what is wrong, but following diff fixes this error:

Fixed in develop branch.

Thanks for the diff!
