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

OF-1209, previously setting "Allowed to Connect" option was a NOOP

This allows plugins and other extensions to directly extend MUC with additional
protocol support, such as support for a Conference Focus on the MUC room JID,
and so on.

* addIQHandler adds a new IQHandler to services and rooms.
* addExtraFeature is the existing function, exposed at the Interface. These
additional features are now shown for both rooms and services.
* addExtraIdentity is the existing function exposed unchanged.

* Removed unreachable code.

* PrivacyLists on first run
There are 2 instances of PrivacyListProvider (one in PrivacyListManager and the other in IQPrivacyHandler)

The issue was : both instances have separate privacyListCount variables, which are filled during PrivacyListProvider constructor (== server startup).
Thus, if at server startup the privacyListCount is 0, and one of the instances adds a PrivacyList, the other will never be informed and discard all changes and reads.

Fix : turn PrivacyListProvider into a singleton.
