Doesn't work with v2 mongo driver

The changes to the insert(), update() and remove() methods mean that it calls back with "mongodb-core" result object rather than the saved object.

I was discussing the upgrade with @microadam recently.

I think it's going to need to be done as part of the v2 upgrade.

Also I'm wondering if you need to depend on the entire mongo driver at all in this module. SInce it only looks like you use it for ObjectID (and tests) you could npm i --save-dev mongodb and npm i --save objectid for a lighter install footprint.

As an aside, quite a lot has changed in the driver from v1 to v2. The method names are very clunky and it seems to be a less user friendly API in my opinion 👎
