* New code in shell scripts required killing systemctl in images
* Added tests for the quick IPv6 env hack I made a while back
* Stopped requiring the need for update.sh to copy gravity for alpine
* (moved modifications to dockerfile)
* One step closer to unified start script for both OS versions
* Optimzed some test code
- Case on IPv4addr was incorrect, gravity now requires it instead of piholeIP file
- debian:jessie no longer had dnsutils dig? odd.
- py.test always pull the latest docker images to help reveal base image changes like above
- py.test stubbing of gravity was acciently not present in debian arm's start.sh
- pihole submodule using development branch latest
