Every plugin that adds to the Admin panel has the admin plugin as
an implicit dependency. Make sure that the admin plugin is loaded,
before any of the other plugins are loaded.

When a plugin fails to load, don't try indefinately.

- Plugin Monitor moved to different class
- Methods that operate on plugin.xml files moved to utilility class
  (and made to work even when plugin is not yet loaded)
- Plugin monitoring now loads plugins more efficiently by:
-- Observing parent/child hierarchy (allowing for one-shot load)
-- allowing for concurrent plugin loading
- Dev plugins are now processed as if they were ordinary plugins
- Plugin canoncical naming is now used throughout the code (fixes
  case sensitivity bug)

When there are multiple plugins loading at the same time, they can
concurrently attempt to add models to the admin console. To prevent
concurrency issues, those methods are made synchronous.

* 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

We had a user run into an issue where the ldap password was longer than
what the input field allowed. Size has been increased to a more liberal
maximum.

Eclipse project: Add extra plugins

Eclipse project: Add as many plugin source directories and their libraries as possible. Unable to add rayo / clustering due to class collisions.

OF-1128: New plugin to resize vCard-based avatars

Added logo's and documentation.

This commit adds a prototype plugin, based on code provided in the
Ignite Realtime community: https://community.igniterealtime.org/thread/58477

Update eclipse project file to reflect changed list of jars. 

Update eclipse project file to reflect changed list of jars. Verified as building and running under Eclipse Luna.

OF-1126: Abstract implemenation should not change signature

The abstract implementation of GroupProvider should not hide the thrown
clause as defined by the createGroup() signature.

OF-1120 Additional fix for the default behavior

To represent a stream ID, Openfire defines the StreamID interface. However,
that interface is hardly used. Instead, simple String representations are used
in most places.

StreamIDs should conform to some specifications (notably: they shouldn't
include XML special characters). An implementation of the StreamID interface
is a good place to enforce specifications like that.

This commit replaces all String-based stream ID representations with an
implemenation of StreamID. For clustering/hazelcast, the serialized string
is still being used to exchange data between nodes (I expect that this allows
older and newer cluster nodes to continue to exchange cache information within
the same cluster).

Also in this commit:
- StreamID implementations check for (and escape) XML special characters.
- Duplicate implemenations of the StreamID interface are removed.

Some code refers to streamID while in reality session IDs are implemented. This
commit does not affect those pieces of code.
