1.8.0

NOTE: This version was actually released on 2018-07-08, but the GitHub release was omitted.

• Add Django signals to important events to let users add custom actions (such as email notifications etc.) to those events (fixes #39).
• Provide a Docker container for fast deployment of django-ca.
• Add the CA_CUSTOM_APPS setting to let users that use django-ca as a standalone project add custom apps, e.g. to register signals.
• Make the otherName extension actually usable and tested (see #47)
• Add the smartcardLogon and msKDC extended key usage types. They are needed for some AD and OpenLDAP improvements (see #46)
• Improve compatibility with newer idna versions (".com" now also throws an error).
• Drop support for Django 1.8 and Django 1.10.
• Improve support for yet-to-be-released Django 2.1.
• Fix admin view of certificates with no subjectAltName.
