v3.1.0 - More features and improvements

 - Improved Dockerfile

    - Docker's `onbuild` images are seemingly deprecated. Now manually running `npm install` and copying
      required files to the image.

    - Updated from NodeJS version `8.11.4-onbuild` to `12.16.1-alpine3.11`

    - `config.json` is now a volume inside the container, allowing it to be updated with a simple `restart` instead
      of rebuilding the container

 - Added `publishonce` feature, which causes the script to publish a feed update immediately, then exit.

 - Added `repository` to `package.json` to silence `npm` errors.

 - Created `run.sh` management script, which will make it much simpler to use the dockerized `steemfeed-js`.
   Large portion of the run.sh code is based on https://github.com/Someguy123/steem-docker `run.sh`

    - Easy install docker with `./run.sh install_docker`

    - `./run.sh start` intelligently builds the docker image if it doesn't already exist, then creates and runs
      the container with the appropriate `docker run` flags.

    - `./run.sh publish` uses the `publishonce` steemfeed-js feature, combined with a docker container which is auto-removed
      after it finishes - no mess to cleanup :)

    - Various other features (see README.md and `./run.sh help`)

 - Added a `.dockerignore` file, which ensures `node_modules/`, `.env` and `config.json` never get sent to Docker's
   context. Speeding up the build, and preventing active keys etc. being stored inside of an image.

 - Updated README with new `run.sh` instructions for managing dockerized steemfeed
