Not all Commons links in the json output is URLencoded. In this release some additional lines were added to urlencode those lines.

In this release, a new function is added to check an EntitySchema directly from WDItemEngine. Until now validating ShEx was done with WDFunctionEngine.check_shex_conformance, but here the wikidata item needed to be fetched twice first as an item to validate and then as an item to update. By moving the function to be part of the WDItemEngine, the function uses the wikidata item fetched for update.
