Title: Allow NestedModel and Object editors' form options to be extended/overridden.

I wanted to be able to override the fields rendered and template used by the nested form.

Contrived example:
```javascript
new Backbone.Form({
schema: {
address: {
type: "NestedModel",
model: Address,
formOptions: {
template: JST["address_form"],
fields: ["street_address", "locality", "postal_code", "region", "country"]
}
}
}
});
```
