- Sync with latest CVS version + gajim patches.
- streamErrorHandler disabled. If you want enable it - unrem it at line 66 of
  dispatcher.py
- TLS re-enabled. Should work fine now
- disconnection TLS plugout re-enabled. Didn't successed in reproducing
  problem though so maybe not fixed.
- My temporary fixes replaced with CVS ones.

gajim connection.py changes (in chunks order):
- getTags is incorrect. Replaced with getChildren
- browseAgents is absent from xmpppy. Fixed with manual node send. Made use of
  buildReply method and con argument
- formatting fix
- crude fixed register problem. I do not know how to do it properly. It is
  client stuff. Honest! I have no idea how to make it non-blocking and yet make
  library to fallback to older protocols.
  getInstructions() moved to xmpppy
Thanks Alexey !
