Updated the XEP-0085 plugin.

Can now be used as so:

>>> msg['chat_state']
''
>>> msg
<message />

>>> msg['chat_state'] = 'paused'
>>> msg
<message>
  <paused xmlns="http://jabber.org/protocol/chatstates" />
</message>

>>> msg['chat_state']
'paused'

>>> del msg['chat_state']
>>> msg
<message />
