Small bug in IQVersionHandler

org.jivesoftware.wildfire.handler.IQVersionHandler tries to parse all IQ stanzas that have the “jabber:iq:version” namespace (XEP-0092). The handler doesn’‘t take the IQ type into account. It should only try to parse IQ type GET stanzas though. The current implementation can fill up the logs with stacktraces, because clients will respond with RESULT typed stanzas to version-request that are made on behalf of the domain. I know, this isn’‘t a biggie, but it’'s a little annoying. Can you include a IQ-type check in IQVersionHandler?
