Gets thrown every time converse learns of a supported server service.
Useful when 3rd party code wants to use API methods that depend on the service
being discovered first.
- Add new config option csi_waiting_time for CSI support.
- The auto_away and auto_xa options won't send out CSI stanzas if csi_waiting_time is 0
- Update docs and add tests for both features.
* Update the docs to mention the new ``authentication`` option.
* Update failing tests due to ``prebind`` being replaced with ``authentication``.
* Rename 'manual' value for authentication to 'login' since it's used in both manual and auto cases.
This caused a bug whereby a chat box would open only on chat state
notifications.
Also refactored the chats.open and chats.get methods so that they now reuse the
same map function and so that chats.get can now return any chat box and not
just already open ones.
Updated the tests to properly test this and updated the docs.
* Let contacts.get() return all roster contacts.
* Also, add "open" method for the chats API.
* chats.get will now only return a chat box if it's already open.
