Currently the wbsearchentities API returns an url field for each search result. It contains the URL for the wiki page of the entity, e.g. https://www.wikidata.org/wiki/Q9351.
Proposal: Add a new concepturi field with the concept URI, e.g. http://www.wikidata.org/entity/Q9351.
Why? We actually need this for the unitsuggester (see https://github.com/wmde/ValueView/pull/184) and it's probably useful in many other (external) use cases.
