Make live stream tests work better.

Browse source 
SleekTest can now use matchers when checking stanzas, using
the method parameter for self.check(), self.recv(), and self.send():
    method='exact'      - Same behavior as before
           'xpath'      - Use xpath matcher
           'id'         - Use ID matcher
           'mask'       - Use XML mask matcher
           'stanzapath' - Use StanzaPath matcher

recv_feature and send_feature only accept 'exact' and 'mask' for now.
