* Submodules of pi-hole source for copying into docker images
* git submodules...yuk.
* debian builds and runs pi-hole apps/configs on jessie docker
* useful base line for merge and testing upstream updates
* Linux x86/64 image, would like to try raspian ARM docker image base too
* WIP alpine dockerfile
* will need more custom lighttpd config(s) at a minimum
* again there is an ARM alpine version so running on pi is future possibility
