OF-1162 Update postgresql JDBC driver to 9.4-1209

Note: this is the 'v4', which is Java1.6 compat

This commit introduces a new AuthProvider and UserProvider that, similar to the
HybridAuthProvider and -UserProvider can be configured to use more than one backend
store. Where the Hybrids iterate over all of their providers in an attempt to
fulfill a request, these new 'Mapped' variants will first determine what provider
is to be used for a particular user, and will then operate on only that provider.
This is useful where particular users are required to be restricted to specific
backends.

OF-1157

- Fixed: Send a presence by affiliation change

OF-1152: Ensure that raw XML is logged;

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

Going back to Java7 for Debian  OF-1115

  o delay adding socket interceptors until the pluginManager is ready
  o Correctly interpret the sent/received messages

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.

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.

Update to last version

Allow specifying a different network interface for the admin console via the "adminConsole.interface" configuration variable. If empty uses the standard interface configuration.

Forced set of JAVA_HOME

OF-1150: muc#roomconfig_allowpm

* 'override' defined just once (and set to false)
* a plugin can be skipped by setting a property 'plugin.pluginname.skip'
  to true (eg: -Dplugin.broadcast.skip=true)
* plugins that are built set the property above, to prevent rebuilding
  during the same Ant invocation (speeds up parent/child plugin builds)

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.
