add Dockerfile for development
Created by: nikolas
This adds a Dockerfile so you don't have to install all of Plinth's required debian packages on your host machine in order to run it.
Let me know if you have any suggestions.. I just thought this could be a good alternative to VirtualBox / KVM. It also provides a place to document what's actually needed to get Plinth running.
I've added some instructions on how to run this to the INSTALL file.
docker build .
docker run -p 127.0.0.1:443:443 [image-hash]
