Cumulative patch:

Browse source 
* Factor out invokeOnInit() method from Node.init() in order to implement onInit() invocation
  for the embedded database.
* Make properties starting with an _underscore transient in the embedded database,
  mirroring the behaviour of the object relational storage.
* Keep filter.additionalTables from being included in prefetchNode() queries, fixing bug 472.
* Some minor code cleanup and simplification.
