* Populate browsable API raw data form with submitted request data in response to an update.

* Remove fields from browsable API raw data that are set implicitly based on URL / parent object.
* Fix issue where a group/host could be assigned to a different inventory.
* Update validation to load values from existing instance if not present in new data; allows PATCH requests to succeed.
