Provide property '_parent' for EmbeddedDocument

[aclowes]

It would be convenient to get the containing document when you have an embedded document. Here's an idea for how to do that. I find I want this sometime when I am passing the embedded document to a function but not the parent.

However, I think people might have a variety of reasons why this is not a good idea. Is this useful or a bad idea?

It is not often necessary, depending increase only, I think.

Ross, I think I will close this pull request for now - maybe revisit it later. I was trying to think through the best way to do this for list fields and didn't have a great solution, as I wouldn't want to iterate over a possibly very long list unnecessarily.

We should be able to do this because an embedded doc will become a BaseList
on introspection so we could use that
