Rel Attributes Filter

Description

The Rel Attributes Filter (rel_attributes_filter) module provides filters for the ckeditor to add rel attributes to links.
Currently, three filters are supported: noreferrer, noopener and nofollow.

This module is based on the Noopener filter module but it adds the filter for noreferrer and nofollow attributes. However, support for the hook_link_alter is not available at this time.
