- PubSub options constants are moved to XEP-0060
    - comments url are generated/parsed according to XEP-0277
    - microblog data can now have the following keys:
        - "comments", with the url as given in the <link> tag
        - "comments_service", with the jid of the PubSub service hosting the comments
        - "comments_node", with the parsed node
    - comments nodes use different access_model according to parent microblog item access
    - publisher is not verified yet, see FIXME warning
    - so far, comments node are automatically subscribed
    - some bug fixes
