--- Module to display an icon with a tooltip such as "Edit this at Wikidata".
--- Icon is linked to the Wikidata entry for the article where this is placed.
--- This message is only displayed if a local_parameter is not supplied
--- i.e. when called from a template, it can be coded not to display the message.
--- The qid of a Wikidata entry can optionally be supplied for testing outside the article.
--- Usage:
--- {{#invoke:EditAtWikidata|showMessage|local_parameter}}
--- {{#invoke:EditAtWikidata|showMessage|qid=<ArticleID>|local_parameter}}
