Sluift was showing payloads coming from a carbon copied message as a series of dom payloads, which was not really usable. With these ElementConvertors, the payload is translated into a much more sensible table Also a minor update to both presence/message events, which now will report the 'to' as well. Seemed handy to have. Test-information: Carbons sent/received messages are formated into a meaningful table now. Change-Id: I5b8943636e09e5377bde76d16970c01df29164d6
