remove of an model from the bikine store

[kwakayama]

By using the LocalStorageStore, I can delete my Model with the 'destroy' method.
When I'm using the BikiniStore the DELETE request throws a 404.
I figured out that BikiniStore uses as default '_id' instead of 'id'.
So I added this line to my model:

 idAttribute: '_id'

Now it works fine with the LocalStorageStore and BikiniStore.
Maybe the BikiniStore should use the id as default.
