Establishes a connection to the XMPP server and performs an automatic
login only if the previous connection state was logged (authenticated).
It basically creates and maintains a socket connection to the server.
<p>
<p/>
Listeners will be preserved from a previous connection if the
reconnection occurs after an abrupt termination.

@throws XMPPException
if an error occurs while trying to establish the connection.
Two possible errors can occur which will be wrapped by an
XMPPException -- UnknownHostException (XMPP error code 504),
and IOException (XMPP error code 502). The error codes and
wrapped exceptions can be used to present more appropriate
error messages to end-users.
