Changeset 4420 for sites/trunk/wordpress.org/public_html/wp-content/plugins/plugin-directory/jobs/class-meta-sync.php

Plugin Directory: Add a cron task to import/update the downloads, rating and ratings meta fields for indexing in Search.
The previous method of pulling the meta keys from a different data-source has proved not to be usable with Jetpack Sync (which we rely upon for Search).
