Twilio Support

[leadstartorg]

Here I made a Twilio support update that could be in the next release: https://github.com/leadstartorg/django-crm-twilio

[DjangoCRM]

Thanks for the heads-up!
Since this feature requires additional dependencies and migrations, it's best to make it optional and simply add a mention (and link) to it in the Django CRM documentation. Please create a PR.
