From: Alan Conway <aconway@apache.org>

Subject: Added cluster URL configuration, defaults to all interfaces.

src/qpid/Plugin.h - added doxygen
src/qpid/Url.cpp,.h - cache string rep, op==, istream/ostream ops.
src/qpid/broker/Broker.h,.cpp - removed getUrl()
src/qpid/cluster/Cluster.h,.cpp - use Url class
src/qpid/cluster/ClusterPlugin.cpp - added --url configuration.
