Merge pull request #104 from ishitatsuyuki/alpine

Several changes:

- Move mailman-web image to python2.7:alpine-3.6 image, which is built on top of apline3.6 and contains the last remaining dependency that wasn't available in 3.5.
- Rename the entrypoint scripts in both core and web to docker-entrypoint.sh, and add them to somewhere on PATH so it is easy to call them in ENTRYPOINT
- Move to `sassc` for django-compressor.
- Set uwsgi uid/gid to string `mailman`
- Use alpine image for postgres database

thanks to @ishitatsuyuki !
