Improve privacy parsing and API. Add NumberUtil

Make 'order' an long

Parse fall-through case's child elements (message, iq, presence-in,
presence-out)

Remove

privacy.addExtension(new DefaultPacketExtension(parser.getName(), parser.getNamespace()));

at the beginning of PrivacyProvider. Was there since day one for an
unknown reason.
