Blacklist module needs to be renamed

I think it would be a good idea for Sangoma and FreePBX to follow the lead of many other projects (Chrome, React, Go, PHPUnit, Gitlab, Firefox, Node, Drupal, Moodle, etc. etc.) and make the simple one-letter change to Blocklist.

Yes, it's a symbolic gesture. No, it won't change anything. I know the term was never intended to refer to skin colour; and it is not "racist" in and of itself. Regardless, it is a subtle everyday reinforcement of the notion that dark is bad and light is good. Doubtless there are people out there more qualified and more articulate than myself that can explain this, if any further explanation is needed.
