Changing attributes after persistance should not write directly to the DB unless specifically saved

Reported by Ben Jackson | November 15th, 2010 @ 04:14 PM | in 1.0.0.beta.21

Currently, when a Neo4j Model is saved, a Java Node is created and that replaces the proxy 'Value' object that handled holding properties and relationships before validation and callbacks allow the data to be saved permanently. After being saved, any attribute can be changed and will be immediately written to the DB.

To solve this, I need to refactor the code to make it so that attribute assigning never goes straight to the DB, but specifically requires a #save, like ActiveRecord.

At the same time, some refactoring will be done to make sure that transactions and type conversions are only ever used when necessary, e.g. when saving and not when validating.
