API changes for the Entity CRUD API since BETA 2:
* The entity controller resetCache() method function signature changed in core and so in the Entity API's controller. See #651240-38: Allow modules to react to changes to an entity for details.
* The faces API has been removed and so the extendable entity class, as using that was not suggested anyway. See #981302: Please remove faces. To ease migration the "EntityDBExtendable" class is still available, but deprecated + it is not extendable any more.
* The "EntityDB" class has been renamed to "Entity". For backward compatibility "EntityDB" is still available, but deprecated.
