MongoDB ops appear to store redundant data

[bfirsh]

This is a small issue, but the MongoDB schema seems unnecessarily verbose:

{
  opData: {
    op: [
      {
        p: [
          "text",
          611
        ],
        si: " "
      }
    ],
    meta: {
      source: "b1c6063989dbca821fd9ded844031305",
      ts: 1356560181754
    }
  },
  _id: {
    doc: "draft-text-b2aa543046d47579aad4738a",
    v: 2
  }
}

Perhaps the opData object could be flattened into the root object? This could be changed in a backwards compatible way by checking for the existence of the opData object.

(cc @zamfi - I think you might know the answer to this!)

So you're just talking about the opData wrapping object, or did you have something more in mind?

Since we don't have _id fields in ops, I think removing opData is a good idea.

Yep - I just meant removing the opData wrapping object. I'll put together a pull request.
