Blogger Importer

Running the Blogger Importer in PHP 7 throws the following warning:

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; Blogger_Importer has a deprecated constructor in /xxxxxx/wp-content/plugins/blogger-importer/blogger-importer.php on line 44

Another user reported this months ago, but it's not fixed yet.
