Demonstrate unwanted record sharing.

By adding a pingbacks relationship and not modifying it in any test, we
should end up with an empty array in all serialized Posts, i.e.

    {
        "post": {
            "comments": [
                {
                    "title": "Wouldn't a more lightweight...",
                    "user": null
                },
                {
                    "title": "This does not seem to reflect...",
                    "user": null
                }
            ],
            "pingbacks": [],
            "title": "A New MVC Framework in Under 100 Lines of Code"
        }
    }

However, what we get is

    {
        "post": {
            "comments": [
                {
                    "title": "Wouldn't a more lightweight...",
                    "user": null
                },
                {
                    "title": "This does not seem to reflect...",
                    "user": null
                }
            ],
            "pingbacks": [
                {
                    "title": "Wouldn't a more lightweight...",
                    "user": null
                },
                {
                    "title": "This does not seem to reflect...",
                    "user": null
                }
            ],
            "title": "A New MVC Framework in Under 100 Lines of Code"
        }
    }
Consider relationship for embedded hasMany records.

When serializing a relationship, the previous algorithm serialized all
records in _all_ has-many relationships, not just all records for the
specified relationship.
Only serialize has-manys that are embedded

Fixtures must have ids
The owner record is now an argument passed to findMany on the adapter

While writing an adapter for my django backend I was unable to
build a valid url for my hasMany relationships because the owner
was not easily accessible. Going forward the owner will now be an
argument available for custom adapters like the one I ended up writing.

example of how my REST api would lookup hasMany relationships:

If I have a person with many occupations I would look them up like so

/people/1/occupations/

Notice the id 1 above is actually the owner of the occupations (not a
occupation id from the ids array that is passed into findMany)

Instead of passing each id like the built in RESTAdapter the url above
just expects the owner will know how to find each occupation
