Use XMPP Ping (XEP-0199) instead of white space ping for keep alive. [#15] This patch introduces the use of XMPP Pings (defined in XEP-0199) for pinging the server instead of just sending white space messages to keep the connection alive through NAT routers. It also adds the feature of disconnecting if three pings in a row are sent unanswered. [#15 tagged:committed responsible:Hallski state:resolved] committer: Mikael Hallendal <micke@imendio.com>
