Add `rel=”noopener”` or `rel=”noreferrer”` to links

Following Google’s directions from Lighthouse, it would be helpful to for the FaithLife Refftagger add the tags rel="noopener" or rel="noreferrer" to the links to biblia.com.

This is something that could go on the js file (https://api.reftagger.com/v2/RefTagger.js) and be advantageous to all users.
