Minor style fixes

### Reset ul list style types inside notes

Because notes are themselves `ul`s, lists inside of notes started at the wrong depth, so this resets that.

Closes #259

---

### Style all blockquote children, not just p

Makes styling of non-paragraph text, such as lists, inside blockquotes consistent.

Closes #1939

See merge request !949

Revert "api: add 'system', 'upvote', and 'downvote' fields to note queries"

This reverts commit dd4fee5f.

See merge request !950

This reverts commit dd4fee5f.

Closes #259

Closes #1939

Note query information

The 'editable' field is required to be able to distinguish system-created notes from user comments. The 'upvote' and 'downvote' fields are so that endpoints don't need to duplicate GitLab's logic for what an up or downvote is.

Update docker documentation to use only one docker container

I updated documentation to use only one docker container with manually specified path to the persistent data. The container is named `gitlab` and the image will be put in GitLab organisation: https://registry.hub.docker.com/u/gitlab/gitlab-ce/

- [x] Add VOLUMEs to Dockerfile
- [x] Removed all other Dockerfiles (moved everything from docker/single/ to docker/)
- [x] Create DockerHub repository for GitLab CE
- [x] Reword README to use single image
- [x] Push images (manually) to the repository
- [ ] Push to GitHub
- [ ] Enable Automated Build
- [ ] Integrate tagging and pushing of the image with GitLab CI
