Updated Service.version and Version.vcl to use new Model.create
Added convenience methods to Service for fetching details and active version number
Bug fixes:
Compare attrs and _original_attrs before saving. (Without this check, calling .save() on an instance without changed attributes makes a PUT call with no data. Then instance.attrs is set to the error response for an incomplete API call, e.g. {"msg": "Missing parameter", "detail": "param is missing or the value is empty: item_value"})
