OF-1236 Handle and generate single equals sign in SASL exchanges properly

OF-1182 remove Release News, expand Blog

Although the RFC doesn't explicitly appear to say this, the SASL profile for
XMPP has historically used "=" as a null indicator in all cases. This patch
builds on Christian's to ensure this is properly checked and handled in
challenge and client-sent cases.

OF-1104 Ensure SCRAM uses AuthProvider API

OF-817 Persist entire MUC stanza

OF-355 ldap.authorizeField is ignored in LdapAuthorizationPolicy

OF-1123 Respond to incoming streams with the right domain

Openfire previously would respond to all incoming domains with the IM domain,
this patch examines and validates the "to" attribute on inbound streams and
responds accordingly.

OF-1212 Oracle database issues

OF-1217, this change was created by the install4j GUI to update the config
to the current-release (6.1.3) schema.

Refactoring work done in 4.1 release of Openfire lead to an introduction of a requirement on `JiveSharedSecretSaslServer`

When a user is created due to successful authentication, now calls the full process of user creation, including firing events for plugins. (#689)

OF-1235 Fixes user_created event not being fired on user creation due to auth.

OF-1214 Update MAM (XEP-0313) to support :0 and :1 versions

OF-1171 Update message routing to RFC 6120

Various non-conformances in message routing caused some odd behaviour where
combinations of outgoing PEP events failing to be delivered could cause
errors to be delivered to all available clients.

This fixes message routing for three cases:

* Headline messages sent to the bare JID are now broadcast.
* Headline emssages sent to an offline session are discarded.
* Groupchat messages sent to a bare JID are handed to offline processing,
however these should not occur.
* Errors sent to the bare JID are discarded.

OF-1213 Add extension points to MUC

SPARK-1803 Can't use usernames with non-latin symbols

in the settings there is now a switch allowing to add complete stanza to
the archive for muc conversations

OF-1223 sort load of ofOffline by date

OF-266 fix image paths for fastpath form UI

OF-1229 Safeguard JDBC.executeBatch() calls on empty batch

OF-955 updated the HSQL library and it introduced a JDBC requirement that
executeBatch() calls actually have batched items to do.  It appears there
is no API available to check for if batched statements have been added, so
we hack in a simple sentinal to safegaurd calls to `executeBatch`.  Thankfully,
only PubSubPersistenceManager.java uses this API.  Otherwise, an option is to
set `allow_empty_batch` on the connection parameters.

OF-1227: Plugins should be able to have proper servlet filters.

OF-1201: Complete context if an exception is thrown when setting read listener
