Deploy a Docker image using Travis (#503)

* Add Docker deployment

* Missing colon in if statement on docker_deploy

* Don't deploy both PyPI with Docker every time

* Remove tagged commit option for Docker deploy and add a TODO on how to address our tagging system

* Add TODO to change Docker deployment to run only on tagged commits (and not on every commit to master)

* Typo in $DOCKER_USERNAME

* Update README and only push to Docker on tagged commit

* Add Docker build status

* Undo Docker badge since we don't have automatic builds

* Update start_docker.sh

* Bump version to 0.2.10

* PyPI defaults to Python 3.7 minimum, need to specify Python 3.6
