npe.

OF-1475: Update to Hazelcast 3.9.2.

OF-1472: Add basic support for XEP-0157.

OF-1471: Terminate upon invalid Stream Management data.

Allow remotely connected servers to subscribe to local pubsub nodes

OF-1469 New plugin: XEP-0215 External Service Discovery

OF-891: Ensure that the clusteringStarting/clusteringStarted flags are correctly set when clustering starts.

When a client tells us that it received an amount of stanzas that's greater than the number of stanzas
that we've sent it, the stream should be terminated. Similarly, we should not allow a client to resume
a stream when it tells us it received more data on the old stream than what we've sent it.

* OF-1467, Check nodeRoutes.containsKeys(key) to avoid Null Pointer Exception in ClusterListener, nodeCleanup, when there are no sessions on the node to cleanup

* Good point. Tweak to fix as per suggestion.

WebSocket endpoint should allow null path.

OF-1468 Group Chat History returns one message too many

Currently the endpoint is only available via ws://host:port/ws/

It will now also be available via ws://host:port/ws

(note the lack of the trailing slash).

URLs without trailing slash seem to be the standard for BOSH and WebSockets and are also used by XEP-0156.

 This commit increases interoperability.

When specifying “Show a Specific Number of Messages” for Group Chat
History Settings, the user get one message to many. For example, if 10
is specified. the user get the last eleven messages in the room.

OF-1460, Session Row jspf has a Hazelcast related bug. It assumes that all sessions are LocalClientSessions. But, in a multi-node hazelcast enabled openfire environment, (#997)

there may be remote (not local) sessions as well.  The bug is a cast of sess to LocalClientSession, but that isn't always appropriate. Session Details and Session Summary jspf pages use this jspf file

An option has been added to the registration plugin that allows an administrator to configure
that all newly created user accounts will be locked out automatically after a certain amount
of time has passed.

Shoutout to @jadestorm for having the foresight in 2008, making this possible. :)

* Add install4j support to the Maven build.

Using the 'install4j' profile on a server that has a suitable install4j and JREs, Maven can now
generate install4j builds, using: mvn -P install4j clean package

Note that Maven, even without the install4j profile, will no longer output the build artifacts
in /target. Instead, these are now outputted into /distribution/target/distribution-base/

* Make Ant build work with changed Maven structure.
