Replace Vagrant with Docker

This replaces the underlying build system with one based around docker.
This is for the following reasons:

1. Portability - Builds can be run on cloud services without spinning up
a second VM.
2. Reduced Overhead - There is a non-negligible increase in compile
times when you are running in Docker vs VirtualBox.
3. Coolness - Docker is cool, I wanted an excuse to use it.
