Subject: [PATCH] Create improved Dockerfile with volume mounts for storing
 data

* Add volume mounts to Dockerfile to enable persisten storing of
  database and tokens when using docker
* Makefile helps with cleanup and building the Dockerfile
* Startup fires the predictify runtime inside the container
* `.dockerignore` contains files that are not needed by the docker,
  e.g. files that would otherwise slow build process down
