New changes to include several features:

* Now the manager does not de-serialize attributes when the session is read from the couchbase repo. The attributes are placed serialized (byte[]) and then are de-serialized when requested. This feature saves some time (attributes are not de-serialized if not needed in non-sticky and not serialized in all cases if not used) but in sticky doubles the session size (every attribute is stored in the session serialized and de-serialized).

* The previous workaround to fix CDI problems in glassfish v4 is avoided because now the attr is always de-serialized in the correct stack (when the attribute is got, set or removed).
Changes to make the session available at inactivity timeout
and, therefore, has complete access to session and attributes
at that time. This way all the session/attribute listeners are
executed properly.
