update path to some files so they match the new structure [it is far from complete and of course it is vital to have the paths fixed before 0.7]

It will help in resolving locking problems

- 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 !

make gajim bootable if not config available. this code is temp but seems to fixes the pb. plz hack it so it meats your taste

allow focus in all parent widgets in tabbed chat window to avoid the dotted rectangle on History button

add new contact dialog code cleanup and some GUI fixes:\nProtocol combobox is disabled if uid is empty\nguess_agent() doesnt change to Jabber if not ICQ\nBecause of massive usage of get_widget() I self'ed them [it's ok this dialog dies soon and it is always better to do less glade parsing

removing extra identation. I also want to mention that the previous commit shouldn't have had all those files. It was by accident. Anyways the previous commit also fixed a GUI bug for the Groupchat: now groupchat window and chat window use *different* hboxes
