Removes a ton of duplicate code, mostly related to MUCItem being duplicated in MUCOwner and MUCAdmin, but also some other duplicate code. Make MUC code use XmlStringBuilder. Add ELEMENT and NAMESPACE constants to the appropriate places. Also add "static <MUCPacketExtension> getFrom(Packet)" methods. Make some MUC classes implement Element.
