OF-1156: Be consistent with the contents of DefaultCache with the HZ cache

Going back to Java7 for Debian  OF-1115

Hazelcast clustered cache implemented by MapProxyImpl by preventing null
keys and values being added. Also document this behaviour in the Cache
interface.

Will build on bamboo + debian with java7 as well

 * will maintain this on the ignite bamboo server as a symlink

Add spanish translations

Also reorder other translations in the same order as english ones.
Now the file has the same number of lines as the english one to be able to find new items to translate easily.

Update to last version

Forced set of JAVA_HOME

OF-1150: muc#roomconfig_allowpm

OF-777: Workaround for CSFR with file upload.

* OF-477: SASL realm should be XMPP domain.

* OF-477: DigestMD5-specific Realm property.

OF-1125: StreamID should be Cacheable.

Fix for Monitoring Plugin Wrong JID Returned

OF-477: SASL requires FQHN (not XMPP domain name)

OF-1132: Ensure that retreived messages have a namespace.

OF-1129: Increase maxLength of input fields

OF-1125: Should use StreamID class instead of String.

OF-1111 Rethink RPM build and versioning

Changed so that correct JID is returned

Include correct affiliation and role after revoking MUC membership.

Sasl.createSaslServer() explicitly states that the value of serverName
must be a fully qualified host name.

Allow JSP compilation with developmentMode=true

Use the JasperInitializer in place of the JettyJasperInitializer across the code base (Http-bind and JMX web plugin).

Bug fix to allow compilation of JSP pages for the admin console when running with -DdevelopmentMode=true.
Fixed by adding jetty-annotations of appropriate version and using the servlet container initializer inside there.
Includes a change to mark index.html as the welcome page rather than the jsp to avoid bypassing context security in development mode.

* Added: Add a group with role to a chat room
* Added: Occupants endpoint for chat room
* Fixed: Admin and Member list to group endpoint

If no 'xmlns' is set for the stanza then as per XML namespacing rules it would
inherit the default namespace, which is wrong (see XEP-0297).

* Added occupants endpoint to restAPI plugin
