Add caching support to xep_0030.

Browse source 
New plugin configuration options:

    use_cache    - Enable caching disco info results. Defaults to True
    wrap_results - Always return disco results in an Iq stanza. Defaults
                   to False

Node handler changes:

    Handlers now take four arguments: jid, node, ifrom, data

    Most older style handlers will still work, depending on if they
    raise a TypeError for incorrect number of arguments. Handlers that
    used *args may not work.

New get_info options:

    cached - Passing cached=True to get_info() will attempt to load
             results from the cache. If nothing is found, a query
             will be sent as normal. If set to False, the cache
             will be skipped, even if it contains results.

New method:

    supports() - Given a JID/node pair and a feature, return True
                 if the feature is supported, False if not, and
                 None if there was a timeout. By default, the search
                 will use the cache.
