A couple fixes
Details:
* Attachments in forwarded messages is now have spacer just like text
* Fixed zero-id error in groupchats (lol, how many times it was fixed)
* Probably fixed error when user has handled when he was offline (not in Transport dictionary)
* A little code cleanup in captcha_forms.py, mod_iq_register.py and other files
* Extended groupchats debug. There was no jids for whom groupchats were created
* Added priority for ujson usage instead of simplejson (it faster)
* Fixed a little typo in runThread() and also added 3 retries
* Forced "account.setOffline"  method call, because it wasn't called at all
* User will be deleted from database if record exists (now i wonder why i did it)
* Fixed socket.timeout in utils.getLinkData (vk, i "love" you!)
* Extended xmpp.DataForms() support in utils.buildDataForm()
* Fixed AttributeError() in mod_xhtml
* A little translations fixes
Well, that's a really huge list for project that not-supported-anymore, but project should NOT have errors when
it development is stopped.
