This fix reverts behavour to reset the web contexts handler collection as it removes the webservices added by plugins at class construction time.

OF-869: Upgrade to latest Jetty (9.2.7)
I would like to pull this right now as I am currently investigating why Jetty is no more working in plugins. I would like to resolve any issues with this upgrade at the same time

OF-879: Update hazelcast namespace, dependencies

Revert fix for OF-874 because it introduced a critical regression.

OF-881: NIOConnection Thread Deadlock when two clients in each others roster simultaneously disconnect

Inject video HTML into document by API

Added shared scrum board (post-it notes) Openfire Meetings Collaboration Application
Added "disable cursor" feature to Openfire Meetings Collaboration API
Added "ofmeet.js" and "ofmeet.css" to enable Openfire Meetings to be used as an API in other web applications
Provided webcomponent to wrap Openfire Meetings API into an HTML tag <openfire-meetings>
Updated chrome extension to 0.0.3

Appearently there can only be one ServerItemsProvider. What happened here is that disco#items requests were now routed to SessionManager, which returned an empty result, which means service discovery fails.

It seems like Openfire can only host items for the whole server, not for single users, so the real fix needs some more investigation.

ofmeet plugin version 0.1.1

Added co-browsing to collaboration api
Moved collaboration api to chrome extension for co-browsing
Updated chrome extension to 0.0.2

OF-874: Fix NPE if from/to is missing

* Repackaged the classes in the Hazelcast plugin to use the project's namespace (org.jivesoftware.* rather than com.jivesoftware.*)
* Updated to latest HZ release (v3.4)
* Updated the name of the default clustering plugin class, used by reflection to initialize the hazelcast plugin (if present).
* Updated docs per community feedback

* Updated JAR file dependencies for Jetty 9.2.7.v20150116
* Extended max HTTP header size to 32k (jetty default is 8k), and added a property to configure it as needed.

Returns an empty iterator if the inbound packet is incomplete.

OF-874 disco#items request SHOULD return connected or available resources

OF-876 IQRosterHandler does not respect error cases in RFC 6121 § 2.3.3.

OF-875 Roster requests to bare JID of the user are not responded

OF-878: NPE in MINAStatCollector

OF-877: Cleanup BOSH start/stop/restart

Fixes a race condition where (apparently) the removeSession method is
invoked before the addSession method has completed.

Update the BOSH connector (HttpBindManager) to properly initialize and
restart after applying a configuration change.

OF-626: Incorporate review feedback
