Fixes for disconnection problems detailed in http://github.com/fritzy/SleekXMPP/issues/#issue/20

Fixes to both ClientXMPP & xmlstream.  ClientXMPP was not tracking the changes to authenticated and sessionstarted after the client was disconnected.

xmlstream had some funkyness with state in the _process method that was cleaned up and hopefully made a little cleaner.

Also changed a DNS issue that was occuring that rendered me unable to disconnect.  I would recieve the following error upon reconnect.
Exception in thread process:

Seems I was getting this error when calling line 99 in ClientXMPP.  You can't bit-shift a 1 and a string and this is why this error is coming up. I removed the "SRV" argument and used the default of 1.  not sure exactly what this should be so it may need to be fixed back before it's merged back to trunk.

The line in question:
answers = dns.resolver.query("_xmpp-client._tcp.%s" % self.server, "SRV")
