Lance Stout a8b948cd33 SleekTest may now run against a live stream.
Moved SleekTest to sleekxmpp.test package.
Corrected error in XML compare method.
Added TestLiveSocket to run stream tests against live streams.
Modified XMLStream to work with TestLiveSocket.

Presence -- Create a Presence stanza object.
check_stanza -- Compare a generic stanza against an XML string.
check_message -- Compare a Message stanza against an XML string.
check_iq -- Compare an Iq stanza against an XML string.
check_presence -- Compare a Presence stanza against an XML string.
stream_start -- Initialize a dummy XMPP client.
stream_recv -- Queue data for XMPP client to receive.
stream_make_header -- Create a stream header.
stream_send_header -- Check that the given header has been sent.
stream_send_message -- Check that the XMPP client sent the given
Message stanza.
stream_send_iq -- Check that the XMPP client sent the given
Iq stanza.
stream_send_presence -- Check thatt the XMPP client sent the given
Presence stanza.
stream_send_stanza -- Check that the XMPP client sent the given
generic stanza.
stream_close -- Disconnect the XMPP client.
fix_namespaces -- Add top-level namespace to an XML object.

Create and compare several stanza objects to a correct XML string.
If use_values is False, test using getStanzaValues() and

Some stanzas provide default values for some interfaces, but
these defaults can be problematic for testing since they can easily
be forgotten when supplying the XML string. A list of interfaces that
use defaults may be provided and the generated stanzas will use the
default values for those interfaces if needed.
However, correcting the supplied XML is not possible for interfaces
that add or remove XML elements. Only interfaces that map to XML
attributes may be set using the defaults parameter. The supplied XML
must take into account any extra elements that are included by default.
Arguments:
stanza_class -- The class of the stanza being tested.
stanza -- The stanza object to test.
xml_string -- A string version of the correct XML expected.
defaults -- A list of stanza interfaces that have default
values. These interfaces will be set to their
defaults for the given and generated stanzas to
prevent unexpected test failures.
use_values -- Indicates if testing using getStanzaValues() and
