Fix package_id argument passed to resource_create

The id variable passed in `resource_ckan = resource_create(ckan_instance, id, package.get_resource(resource_name))` was not defined.

Changed to the correct package_id and adopted better naming convention for data packages replacing `package` with `datapackage` (ie. analogous to `dataset` and not just `set`)

Resolves #55
