Feature - Translate all ObjectID fields

[crobinson42]

There are cases where someone may implement js-data-mongodb towards a pre existing Mongo database collection and some libraries (ORM's) that perform relational mapping store record _id's in the ObjectID bson value, ie: { "_bsontype": "ObjectID", "id": { "type": "Buffer", "data": [87,...156] } }.

When using js-data-mongodb, it would be convenient to pass an option to translate all ObjectID fields to a string.

I would apply the logic in the method _translateIds() on line 218 and change the name and all references to it to "_translateObjectIDs()".

@jmdobry If you'll accept this feature, I'll put in a PR. Please let me know.

*re version 1.0.0-beta.1

This will be an option where users can opt in? No breaking change?

[crobinson42]

Yes.

[jmdobry]

And how is this different than the translateId option? It works in the reverse?

[crobinson42]

It would use the same logic inside translateId but for the sake of DRY code, I propose renaming translateId to translateObjectIDs and then running the if... logic on the jsDataOpts.

Renaming an option is a breaking change. Let's see your PR.
